Does anyone know where I can order a adaptor for my remote start unit so I can connect my tach wire to my coils?  I can't seem to get a signal .

 Jon, where is the white wire in a black clip labeled white? Do you think I have an allright location behind my instument cluster for connecting to the tach?  I suppose my last resort is hooking up at the ECM under the hood but I really don't want to hook up there because it is such a mess of wires and I really don't want to make that kind of connection under the hood where I might run into problems down the road with moisture and so on.  What's your oppinion?

I can't seem to find a white wire in a black clip on my drivers side fender well.  If I do find the wire how do I meter it to know if it is the correct one?  Will just a digital multimeter do the job?

   I went and searched past forums and found one on June 13,2002 from 2000 Blazer and he says everyone he talked to and every web-site he was on said his tach wire was white.  He had a conversation with Jeff a Velocity motorsports and he found out that it was a WHITE/ black wire and that did the trick.

set meter to ac current 200 will read bettween2--6 volts   1.ECM is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the tach wire is at pin 20 in the connector labeled "red", and VSS wire is at pin 3 in the connector labeled "black". On the 4.8L, 5.3L, and 6.0L, the tach wire is located at pin 10 in the "red" connector, and VSS wire is located in pin 50 of the "red" connector.

Notes:
If you have a 2000 Classic Pickup, refer to the 1998 Full Size Pickup.

Note:  This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L.
Note: Diesel glow plug, dk. blue(-) located at the instrument cluster. Diesel tach wire is white at the cluster.
*1 The BCM is located behind the drivers side of the dash.  The plugs on the BCM face towards the rear of the vehicle. The parking lights are in pin A5 and the headlights are in pin A11.
*2 Use tan for the drivers door located in pin B4 of the purple plug, and for the passenger door it will be a orange in pin B2 in the purple plug or dk.blue/white in pin B11 of the lt.blue plug, must diode isolate these wires.
*3  ECM is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the tach wire is at pin 20 in the connector labeled "red", and VSS wire is at pin 3 in the connector labeled "black". On the 4.8L, 5.3L, and 6.0L, the tach wire is located at pin 10 in the "red" connector, and VSS wire is located in pin 50 of the "red" connector.
*4  Also found in the purple plug of the BCM.

I just installed a remote start on my 2002 Silverado.  I used the tach wire going into the instrument cluster.  There are 4 screws you have to remove, it plugs into the top and I think it was the only white wire in the plug.  I had to get to the wait to start light there anyway so I had it out.  Splicing in 2 wires instead of one and not run to the ECM.

Chris,  I have my tach wire hooked up to the white wire behind the cluster,  Did you use a module to bypass the Passlock 2?  Did you have to do anything with the KEY SENSE wire? If so where did you find it and connect it to the Passlock 2 bypass module?

Your best bet is you use a module for passlock unless you really know what your doing.  It's not hard but you have understand it well.  Also the modules are mostly self learning now so you won't have to get back in there and change resistor values down the road.   You don't need the key sense for any modules I am aware of.  It is very easy to find the key sense wire anyways if you do need it.

I need to know if my vehicle has to have the key sense output hooked up.  I don't have a clue if it has it or not.  I have a module for Passlock but I think its giveing me problems because of what the directions say and what I have.

What problems are you having?  The truck does not require the key sense output to be hooked up.  The module might, but should work fine without it as long as key is not in the ignition.

Eric,

Yes, I used the CrimeStopper GMATAII module.  You have to if you want remote start.  Basically, you have to measure the resistance of the circuit and dial in the pot on the module to match.  Wasn't hard at all.  I think it takes 2 relays and you have to get the exact resistor to match if you don't want to get a module.  But, at 4-6 bucks a relay and wire and having to have a way to go get a resistor if you don't have a Radio Shack next door, it was worth the 15 bucks I paid.  I did nothing with the key sense and my remote start works fine.  Hope this answers your questions.

Regards,

Chris

I have a IPPME self learning module.  I don't have to measure resistance anywhere.  I think I might need to hook up my key sense wire because I can't get my truck to start.  My Prestige APS-685 according to the directions on how to program the tach input says when the tach signal is learned the lights will flash on and off as long as you hold in the program button, when you release it the lights are supposed to stay on for 3 seconds and go out.  This is supposed to meen that the pickup has learned the tach signal and is out of programming mode.  It does all of this.  When I try to start the pickup with the remote it turns over and then dies.  When I run the diagnostics check the lights flash 2 times telling me that there is a week or no tach signal.  How could this be when I just got done "learning" the tach signal?  My only idea is that the IPPME module isn't allowing the pickup to run and then my remote start unit does't see a tach signal so thats why I get a week or no tach signal on the diagnostics.  Does anyone have any other ideas to my problem?

If there is a problem with your IPPME module, the security light will come on and you will not be able to start the truck even with the key for 20 minuts.

that does happen, but it not for 20 minuits it's more like 5 to 10.  So if my truck does't want to start with the remote it's probably a problem with my IPPME module?  Could it have anything to do with the key sense wire that I don't have hooked up for the IPPME?
