Sweetness! Glad you got it figured out. Alarms and other poor aftermarket wiring jobs always seem to cause all kinds of problems. Usually best to rip that crap out and do it the right way.

Congratulations, I had a feeling that it was from the alarm system. I have to agree with GSL-Addict, the most common electrical issues I find on cars tends to be from people who wire in alarms or stereos or what ever else they purchase incorrectly.

they do not have daytime runners. did you remove EVERYTHING from the alarm system? still sounds like a short leeching power, or need more grounds.(you can never have enough grounds!)

One other thing to mention in regards to the alarm system...

Make sure that when you removed your alarm components that you did not interrupt or leave modified circuits alone. For example, Alarm systems tend to cut off ignition, fuel, starter, ect so just removing it could leaving you with a no start condition because the circuit for those systems was not repaired after removal, perhaps a similar issue is occuring.

Second, if you have DRLs installed by this guy I would first check all the wiring in regards to the lights, start with the blinkers and headlights, cross reference the wiring against the FSM and inspect what looks out of place.

No problem, my mind is very fresh on wiring issues as I am still in the process of redoing my new engine harness to my chassis harness for my car. Hopefully I will have it done soon! I miss my baby!

But yeah, always glad to help out a fellow enthusiast!

I was under the notion that Canada adopted the DRL after 1990?

The red/green wire from the combination (light) switch supplies power to the parking lights when the switch is turned on. Seems like some wire with switched 12v might be connected to that red/green wire somewhere. That wouldn't explain the headlight/ignition/battery problem.

There are two round black rubber-covered main relays. They are under the hood near the firewall on the driver's (left) side. Maybe the alarm was wired into the main relay that controls power to the coils. I believe that is the one nearest the left side of the car. You can see where my MSD switched power is connected to that relay in the picture.

ok well i checked relay's and its all hooked up right and the wire's have not been tampered with. Im starting to think it might be my battery guage inside the car because now it dosent even regester and i have 12 volt's everywhere else....

allthou i can start my car turn on headlight's and turn the key off with headlight's on and it stay's running,then i turn headlight's off and car will shut off........

hey chris i was just thinking, when you were changing out the fuseable links to the second gen fuse block. i noticed that you have one alum...battery cable? see if thats your ground, if so i bet that cable is no good. alum. is very soft and breaks over time. if so i would change it to copper.

copper is a way better conductor.
.
just a thought...

Well that's interesting... Not sure why your headlights are acting like an ignition switch... but interesting none of the less.
