Where is a good source for wiring diagrams and color codes for our trucks? I would like to know the ignition and door wires for my Screw (early gen I, same as 2000 expie) so that I can install a remote start / keyless entry. The unit I purchased did not include vehicle specific info.

 

Try:

http://www.bulldogsecurity.com/wiringdiag.htm

 

Also try " Helms. " I dont have address, it maybe listed in your owners hand book.

Dont know how up to date they are, but in 99, they had complete elect. diag book, but not cheap. I ended up not needing it, but it was very comprehensive.

Good luck....OT

 

Any other ideas? Bulldog did not have a Screw diagram but I printed 3 various models that may be the same and will check when I am under the dash.
Thanks.
