I want to put a remote start on my 2005 Silverado 2500HD Duramax Diesel. I would like to use a 2 way remote start and bypass module that have the data port communication. Maybe GM-SL2 bypass. Which brand remote start modules have the compatible data port? I would like to control the rear defrost and heated seats with the remote, even though the GM-SL2 is supposed to turn them on when temp is below 32 degrees. Where is the best place to buy the hardware? I have researcehd Crimestopper, Compustar, Ultrastart, Bulldog. Any information is appreciated, need some opinions from experienced installers.

We use the Compustar 2W900FM-S systems along with the iDatalink witht he 232 port. IT's a very basic installation and requires way less wiring because of the 232 port installation. Also the Compustar has a diesel timer delay on it so that you don't have to worry about wiring up a delay timer to the vehicle for the wait to start wire. Just program the module to delay start.

That idatalink sounds just like the data port set up I used today on a Buick Rendeavous. A four pin harness connects the Crimestopper remote start to the GM-SL2 module. On this particular vehicle all I had to do was hook up the wire to the OBD2 contector and was all done. It did the parklight,locks,trunk/hatch and tach through the data bus.. Was really slick and fast.. Oh modern day technology....

Thanks for the info Jeff. Do you know if the GM-SL2 data port is RS232 like the the iDatalink and which remote brands besides Compustar are compatable with either of these bypass modules?

Anybody know which wire is the "wait to start " on a 2005 Chevy Duramax diesel?

Dont use it, go with a timer if your concerned. Duramax is so quick most of them wont register...

Thanks for the reply. I have found the tach wire on the power train module under the hood, but not sure where it is under the dash. The Duramax will actually start without any delay unless very cold. The glow plugs are supposed to be a max time of 3 seconds.

Exactly, thats why you don't need to worry about it, most rs units take over three seconds to crank anyway.. There has also been an issue of units not seeing the (-) puls from the wts wire and never cranking.. I just set them as a gas car and off they go, unless the customer requests a time delay.. never had a problem.. The tach is in the harness at the cluster along with the wts and vss wires... real easy to find...

Depending on the RS your using you may have a diesel wait to start delay built into the unit. Compustar's have this feature as a standard feature but requires the programmer to set it up in it's programming.

Does anyone know if the GM-SL2 Datalink is compatible with Crimestopper RS 1905 FM Data Port?
Posted By: ziggyb222
Date Posted: January 09, 2007 at 7:11 AM
I believe all crimestoppers are compatable with the GM-SL2.. I just did a Buick yesterday with the 1304 Crimestopper and the GM-sl2..Slick set up..

I want to control the rear defrost with one of the remote start auxilliary outputs (Crimestopper RS 1905 FM). Does anyone know where the rear defrost signall wire is located? I assume it is a momentary pulse from the pushbutton switch in the climate control section of the dash. I would like to find the easiest access to this wire. Also, would this be a sinking or sourcing signal?
Posted By: KarTuneMan

Pin A8 in the gray connector at the BCM under the dash White wire NEG(-) needs a "latched pulse. This will NOT turn on the indicator light, OR the heated mirrors, but WILL turn on the defroster.

I am quite sure the GM-SL2 will do the driver setting memeory and rear defrost if the Temp is below 32 degrees... Done all through the databus....

Date Posted: January 10, 2007 at 2:14 PM
Yes, the GM-SL2 is supposed to turn on the heated seats and rear defroster if engine temp is below 32 degrees, but I would also like to be able to turn on the rear defroster using the remote.

When you connected the 1304 to the GM-SL2 did you use the Data Link or hardwire?

i have been using the datalink on anything i can.. It seems to be a good set up so far.. I am sure there will be some issues.. But I havent had any yet...

I am planning to use Crimestopper RS 1905 FM remote start module which has DP technology according to their website, but Crimestopper's tech rep says it is not compatable with the GM-SL2 datalink and must be hardwired so now I am confused.
Posted By: ziggyb222
Date Posted: January 10, 2007 at 4:50 PM
I believe it has to be the DP2 technology for the Datalink to work.. so you remote start would have RS-1905 DPII..
Posted By: arhunter
Date Posted: January 11, 2007 at 6:18 AM
That is probably true, but on their website it doesn't show a RS 1905 DPII , only the FM but it says they all have DP technology. I guess I'll ljust hardwire from the GM-SL2 to the remote, only 4 wires anyway. Thanks for the info.

On the Crimestopper RS 1905 FM remote start, the "Diesel glow plug delay" wire has jumpers to select (-) or (+) signals. If not using "wait to start" should this wire be left disconnected or connected to ground or +12V? The only programmable options for "Diesel glow plug delay" are for 10, 20, 30 seconds or monitor glow plug. There is no option to "not monitor" the glow plug circuit. I assume the remote start module looks for a transition from one state to another if the wire is connected, but if not connected and no delay is selected is this signal ignored?
Posted By: ziggyb222
Date Posted: January 15, 2007 at 7:06 AM
I do not use that wire at all.. I just set the remote starter up to dely for 10 seconds i think. The Duramax is only like three seconds for the glowplugs.. I have done a ton of these with no problems with this delay set up.. I have never used the wait to start wire setup.. Hope that helps

Where is the tach wire physically located under the dash on a 2005 Silverado Duramax Diesel (easiest access) ?
Posted By: f150fan
Date Posted: January 21, 2007 at 3:56 PM
It the only white wire going into the back of the instrument cluster.

Absolutely! Easiest one to get at in my opinion. Just take the trim piece off the front of the dash, 4 7mm screws holding the cluster in and like f150fan mentioned, its the ONLY white wire on the back of the cluster. Good luck. ------------- Shaun, we are the same height, that is neat!

I have the lower dash panel off, is there any access to it under there?
Posted By: green6767
Date Posted: January 21, 2007 at 5:24 PM
nope. Its actually really easy to get to behind the cluster. hop up into the seat and put the key in the ignition and turn the car on, move the shift lever down..(put parking break on). pull on the top part of the trim panel above the cluster until it pops out. the whole thing just pops on, and it will pop off just as easy. take it off, set it on the dash. now you have access to all 4 7mm screws to take the cluster out. for all the guys who know exactly what i'm talking about, once you get it down, it gets to be a very easy process to get a reliable tach source for these vehicles.

I pulled the instrument cluster out and got to the white wire. When I check the frequency with the truck idling it is 22.7 hz. According to the Crimestopper RS 1905 FM install manual it needs to be from 70-700 hz to work properly. Has anyone used the tach signal on a Durmax diesel with the RS 1905 remote start? Would it be better to use the smart tachless mode?

I have never had an issue using the white tach wire on the cluster. Use it.....

Finally got a chance to start the remote install last weekend. I am installing a Crimestopper RS 1905 FM with GM-SL2 bypass. Installed the T-harness and wired in an Anti-grind relay and got all the other wiring done. Haven't plugged anything in yet. While I had the dash bezel off, I pulled out the Climate control module to see if I could locate the wire for the rear defroster. It is easy to get to the connector, but many wires in there. It seems like there should be a momentary pulse from the push button to trigger the rear defroster. I would like to control this feature with one of the auxilliary outputs. Anyone have any information on the wiring coming from this module?

I am having trouble programming the remote start module (Crimestopper RS 1905 FM). To enter the tach learning mode, it says to start the engine, and press the program switch 5 times, wait for 5 flashes, but all I get is a solid red led after a few seconds. Am I missing something?
Posted By: brcidd

Did you ground the hood pin switch wire- or open hood if hood pin switch is installed? Can't go into programming mode without it being grounded- also have remote handy and antennae installed so as to push button number 1 (lock) when needed..

I assumed the red LED would blink during programming but apparently only the parking lights blink (just like the manual says!). The tach signal works fine and everything seems to work. Only problem I see now is this: I thought the GM-SL2 was supposed to do driver side unlock priority but it seems to unlock all doors on the first unlock pulse?
Posted By: arhunter
Date Posted: February 04, 2007 at 7:05 AM
The GM-SL2 is supposed to turn on rear defrost and heated seats when engine temp is below 32 degrees. It does not work on my 2005 Silverado. Anyone seen this problem before? Anyone know how to turn these features on with the auxilliary outputs?
Posted By: dre187
Date Posted: February 04, 2007 at 10:44 AM
did you connect both acc wires? the acc wire that powers those features need to be powered by the rs in order for the gmsl2 to trigger them. i used that module on a 03 hummer h2 a couple days ago and it worked fine. if you want to know how to do it through aux outputs, i need to know what kind of remote start your using...although it is easier to just power up the extra acc wire.
Posted By: arhunter
Date Posted: February 04, 2007 at 11:23 AM
The remote start module is a Crimestopper RS 1905 FM. I only see one accessory wire for the 2005 Silverado? I have pin 2 of the high current connector connected to the orange wire in the vehicle (I used a GM-12 T-harness).
Posted By: dre187
Date Posted: February 04, 2007 at 5:31 PM
brown is the 2nd acc wire. you're going to have to use a relay to power it up though since the can also has 2 ignition wires...
Posted By: arhunter
Date Posted: February 04, 2007 at 6:38 PM
Thanks for the info, the brown wire is straight through on the T-harness and not powered up by the remote start module. I noticed that during a remote start (no key), I can manually turn on the heated seats and they come on as well as the rear defroster, so it seems like they don't need the 2nd accessory wire to be powered up? It seems like the GM-SL2 should attempt to turn them on even without the 2nd accessory wire? What I would really like to do is control these two features with the remote start auxilliary outputs but I can't find the vehicle wiring information to do this.
