I want install car alarm system with remote starter to my yukon 2002, but I have problem with a +12v constant, my starter required 5 +12v constant sources.

*main power input+ : for starter module (heavy gauge with 30 amp fuse)

*constatn +12v input: for 10 pin connector primary harness H1 (with 15 amp fuse)

*two cable for the lock and unlock as below image

* anti thief bypass module

So, can I use the ignition harness for all that wires

Yes or run to the battery.

Thank you

I installed remote starter to my GMC 2002 yukon, the keyless entry working well, but the remote starter not working totally.  Is the starter wire in the ignition harness heavy or not, because I found the yellow wire in the ignition harness not heavy wire???!! Can anybody give me an image for the ignition harness with marked these wires.

You need to always use a DMM to make sure the wires you are connecting to are correct. If you were to hook to the incorrect wire you could blow an airbag, burn up a computer, etc. I do not have a picture of it but as I remember it, it is indeed a heavy wire in your truck. Take the shroud off the column, find the ignition switch and you will find all of the wires you need.Installer, IT support, and FFL. I need less hobbies.
