02 Trailblazer, remote starter

I've a 2002 gmc envoy, which is exactly the same engine, chassis..except interior and exterior bodyworks, as far as i know, the stereo does stays on for a period of time unless u iether open the door or shut it off manually. btw, how's the installation of this remote starter on this car? I'm thinking of doing the same project when it gets a little warmer out...thanks, Dh

I installed a Hornet (DEI) alarm/remote starter) in a 2003 Envoy so my wiring should be essentially the same as yours. Might depend on which RS kit you get. The wires you need to locate (and you may have already had to find some of them):

At steering column (big wires):

• 12VDC constant- 2 of them. 2 red wires or one red, one RED / white
• 12VDC accessory #1- brown. Needed for dash lights
• 12VDC accesory #2- orange. The Disk 3.0 calls it ignition #3 but it's accessory. Need for AC/heat.
• 12VDC starter- yellow. Cutting it in half was the very last thing I did. Made me nervous.
• 12VDC ignition #1- pink
• IMPORTANT- ignition #2- white. You will fry your transmission if you don't grab this one!

tach wire- 1-6VAC, not VDC. Take your pick-

• white wire behind speedometer. So much easier than the next option IMHO.
• white wire in C1 Conn at PCM (3 harnesses on left side of engine, blue harness closest to firewall, pin #49

brake wire- 12VDC white wire at brake pedal harness.

neutral safety switch- vehicle itself disables starter except in park and neutral, so I grounded it to frame.

parking lights- Most tables say 12VDC brown wire high in driver's kick. Balderdash. I used PURPLE GROUND wire in light switch harness (GROUND when lights on, not 12VDC. Have to change a jumper on brain to use Ground!).

ground- pick a good bolt behind glove box that holds dashboard to firewall.

included in your kit- hood pin switch. Wire goes through firewall. Disables starter when hood's up so you don't injure yourself when you lean against fender with remote in your pants pocket.

things not to worry about- door pin wires, door locks, windows, headlights, horn, OEM alarm, PassLock. You need an interface to disable PassLock II anyway. Just get an all-in-one interface. DEI, CrimeStopper, Trilogix (BypassKit.com) have them. I've used Trilogix's GMDL-BP on a 2003 Silverado and 2004 Envoy without a hitch. Your mileage may vary. CrimeStopper's supposedly works the seat heaters and front defroster, from what I hear.

If you use a GMDL-BP you're going to have to run the rear defogger wire to the GMDL-BP to keep the engine from dying right after it starts. You might be able to use that wire for both functions, but I'd isolate with diodes before trying it.

This weekend I'm going to try to hook up the front defroster and heated seats. If I'm successful I'll post what I did.

By the way, speaking of Retained Accessory Power: If you use a GMDL-BP and don't use Passive Arming on the alarm, the domelight will be turned off when you arm the system with the remote. Just like using the OEM remote. The big orange accessory wire under the steering column shows 12VDC when the ignition is in Accessory or On, and about 18VDC with the ignition Off and Retained Accessory Power in effect. Go figure. If you need "pure" RAP you can grab one of the wires at the lights overhead by either front door opening or trace them down the "B" pillars. I gave up trying to find it in the kick. Love those guides that say to grab it at the light under the dash.
