03 Trailblazer remote start

Hi I have a Valet 561r and 457GW Data bus interface. I am in the middle of the install but am having a problem finding some of the wires. I have the directwire wiring information in front of me, but some of the wires I just plain connot find. I cannot find the factory Disarm wire, which it states is in the door, and I cannot find any infmation on the factory re-arm wire.

would anyone happen to have a psudo- walkthru for a basic remote start install on a trailblazer? I have the 457G pretty much figured out. it's just the remote start that I'm having problems with.

Thanks

Derrick

I just did my 03 Trailblazer, using the gmdl-bp, hooked the grn& blue from locks on the Rs to the bypass module, you won't have to go thru the door,the databus should handle it for you.

The RS uses the 6 heavy wires , hook these to the heavy wires under column,yellow start wire to the starter wire under the column, Grnd when running hooks to the bypass module, Hood pin to ground.

Using the 457G I believe should handle your arm/disarm,you won't have to worry about finding these in the door. Here's the wiring diagram, disregard the door lock relays ,as i believe the 457g will handle it without going into the door. any questions, contact me Ruffdog@Aol.com

Show Large Image This picture shows the IGNITION SWITCH Harness and Plug location under the dash of the vehicle, this harness exits the bottom of the STEERING Column Cover under the dash. This is the plug that when installing a T-HARNESS, you seperate, and place the T-Harness inbetween. NOTE *** the BRIGHT YELLOW Plug to the LEFT of the IGNITION SWITCH Harness Plug is the AIRBAG Plug, DO NOT TAMPER with the PLUG!!!! Show Large Image This picture shows the IGNITION SWITCH Harness UNPLUGED from the Vehicle. When installing a T-HARNESS, you would plug the T-Harness into both plug and reassemble. This harness hold all needed IGNITION wires and the PASSLOCK 2 wires. NOTE *** if you look close in this picture, you can see the PASSLOCK 2 wires: YELLOW (+), ORANGE / BLACK (-) and RED / WHITE (NOT USED!!) Show Large Image This is a picture of the GM-9 T-HARNESS, make sure the T-Harness you recieved looks like this harness. The GM-9 T-Harness plugs into the Ignition Switch Harness that exits the Bottom of the Steering Column. Show Large Image The Male End of this GM-9 T-HARNESS, plugs into the Ignition Switch Harness plug at the Bottom of the Steering Column. Show Large Image The Female End of this GM-9 T-HARNESS, plugs into

where did you go to get that T-Harness?? Also, is that does that handle the majority of the wires for the kit?

Thanks

Thank you all very much. So just to make sure I'm going to ask about all the wires.

Black: Ground

Red: Constant +

Gray/black: Postive dome light circut (??? where is it)

RED / White: Trunk (Not used for blazer)

BROWN / White: Panic output (where is that?)

Light green: negative lock wire (connected to valet 561r)

blue: negative unlock wire (connected to valet 561r)

Violet: Diagnostic plug (connected to pin 2)

blue/white: Ground while in remote start mode (connected to valet 561r)

green: Negative Doot trigger input (supposed to connect to valet.. can't find the proper connection)

Pink/Black: ignition side of Ignition wire at the passkey (Have passlock,  connects to the yellow wire???)

pink: Module side of igition wire (Again, have passlock, connects to yellow wire???)

And for the remote start, I do not have to worry abotu connecting the factory disarm and rearm wires at all (light GREEN/ black and GREEN / WHITE wires on the remote start)

What about the Positve and negative activation inputs?

thanks
