IM not doing the install, but my friend just bought a new truck and he is putting his alarm on in my garage. He has a few questions...

1. Where are the 2 ingnition wires?

2. Where is the tach wire/PCM Pin number.

Any diagrams, pictures, help would be great. Thanks.

I was just told to type, i know nothing more than this. Sorry for the unclear questions.

 

shot u an email, i have diagram u need, but ign, wires are white and pink, 2 seperate harnesses at steering colum above bcm. tach is white grab it behind insterment cluster at plug. also a tip, if it has dual climate control, you will need to feed both orange and brown accessory wires, even if blow moter works, if not it throws codes. just take wire from remote start unit and use 2 relays and split output.
hope this get u started. now my 2004 is data bus, you do know u will need a converter to do locks and if remote start a by pass module?
anyways email me and i'll send wiring cheat sheet.
