newbie, 04 silverado, remote starter

installing a compustar remote starter (2w900fm-as brain is a cm3000-vd) in my truck 04 chevy silverado 3500 diesel 4 door. Would like someone to go over this before i wire it in. i might have missed a few things. especially on the idatalink like ground output when running,ignition,tach output,door status and panic

Although this is a list of the correct wires to hook up. You still MUST test each wire to be sure you have the correct one.  This will prevent much headache in the future, including damage to your vehicle.  Here's some of the modifications I see in your list.

The RED / white wire in the ignition harness needs to be connected to a 12v constant source, not the white wire you specify above.  The vehicle has two red constant wires in which I use both.

You will want to use the supplied relay with the purple wire hooked to the green negative ignition output and the blue wire from the relay to the vehicles white second ignition wire in the ignition harness.  If you don't power up this wire, you will have warning light issues.  You will also want to build a relay using the WHITE/ black accessory negative output as a trigger to power up the vehicles brown second accessory wire. 

For the park lights you should either use the positive output, or the negative output; but not both.  The easiest to find is the negative output, but you will probably want to use a relay. 

I can't check the Idatalink connections as their website is down right now for maintenance.  But I don't think you have the black status output on the right wire.   It should be going to the ground when running wire on the Idatalink module.  IIRC it is blue.

For door sensing, you can use the vehicles domelight supervision wire as a trigger, but you will have to program the open zone warning for 60 seconds to give the delayed domelight time to turn off.

You will want to hook up the glow plug wire to the vehicles dk. blue wait to start wire. 

IIRC the Idatalink module doesn't disarm the factory alarm before remote start.  So you may need to run a wire hooked up to the black status output into the door to trigger the factory alarm disarm wire.

I've always added a relay to the negative parking light output just in case the 200ma output wasn't enough.  I know the factory wire is only 18 awg, but I prefer to be safe than sorry.  So have you ever had a problem wiring it directly?  I'd love to be able to wire it this way if assured there wouldn't be any problems.

Thanks for that tip! 

I haven't done too many of the diesels.  But IIRC the wait to start wire is almost impossible to find in that vehicle anyway.  I believe I've always used a programmed delayed start in the past instead.

Just for future referance. The wait to start on this truck can be found in 2 spots. Under the underhood fuse box. It's blue in a black plug with purple guts.

It's also behind the guage cluster.... same color. Negative. The tach is in the same 2 spots. White 4 cylinder reading.

thanks for the help so far everyone

i'm using a idatalink solo series ads-gm, have to hard wire the unit because there is no rs232 port on compustar

Q1. What does idata link 2-way mode mean? my next 2 questions depend on this.

Q2. door status(-)output white wire on the idatalink does this go tocn3/pin5 door sensing(-) on the compustar?

Q3 tach output(ac)BLACK/ white wire does this go to cn3/pin9 alt/tach sensing on compustar so i shouldn't have to go tothe  instrument cluster white wire

Q4 ignition(+) input green wire on idatalink not sure were this goes on compustar(maybe cn2/pin3 on compustar)

thanks again

i do have the duramax engine and its like 3 seconds for the glow plugs

No, the Idatalink module wants a positive ignition source.  You will want to connect it to the large awg green wire on the Compustar unit.
