ignition help please?
I have an 85 mercury grand marquis that im going to put in the demos. i got a little carried away when gutting it out and snipped a couple wires i shouldnt have. im going to run the starter on a toggle switch, that i can do no problem. The ignition i am also going to run on a different toggle switch. i heard that i only need 4 wires to make the car run, but i dont know which ones those are. i found a wiring diagram online but the colors do not match. Electrical things are my weak point. if anybody knows what wires i need to make it run that would be great. please be as specific as possible like how i can determine what wire is what. please help i am completely clueless and im afraid i might fry something if i do something wrong.

You can figure it out, not so hard. You'll need to power the ignition and the starter. The rest of the wiring won't be needed- no brakes, radio, heated seats, turn signals, etc.
Just make sure the polarity is right- don't wire the battery backwards or you'll fry the ignition. Ditto the starter, but that's easier, since you only have the single "hot" wire on top of the starter to worry about. It's up to you, but I'd leave the stock starter relay in. Best of luck!!
