Re: Wiring problems
I bypass Passkey II (yours) with a gmata II module- $14 off ebay- It is designed for remote starters- but I ground it permanently so it activates with key or remote starter- done it on maybe a dozen GM trucks- works great...you can also do it with resistors if you are handy at soldering and using a DVM.
There is NO bypassing the BCM/ECM because it looks for the security signal from the PASSKEY II-- so don't think you can bypass it with just wires--unless of course you pull out the entire PCM/BCM and run it like a truck out of the 70's . fuel injection HAS to have a PCM- as well as every other controlled feature-- so the bypass of the PASSKEY II is the way to go..
The instructions come with the module- as to which wires to cut and attach. and there is no dash pull....
