Question
gw1500se
I have a 2000 GMC Sierra 1500 4x4 (4.8L), purchased used, with some new odd problems. It started with the service engine light (see my orignal problem here). After receiving a new PWM solenoid but before I had a chance to install it, the odd behavior started. But first before this, was a problem with the power locks. I have an after market security system (Alarm Code) and occasionally when hitting a bump or coming to a stop the doors would unlock for no apparent reason. Sometimes the power lock switch (not the key fob) would not lock the passenger side and other times it would not work at all. I didn't pay much attention to it since it was no big deal. Not sure if that is related but the most recent issue is that when I start the truck and the service engine light is not on, the truck will not idle (stalls). After it warms up by keeping it above idle, I shut it off and it will start with the service engine light back on then run normal. I think there are 2 possibilities. Either the Alarm Code is messing up (if I knew how/where, I'd remove it) or there is a wire harness problem somewhere. It is my guess the problem is more likely to be the latter or at least that is where I want to start. After that long winded explanation my question is where can I find a map of connector locations so I can check them all out? A corroded connector is the most likely culprit. The wiring diagram does not say where the connectors physically are located. TIA.
