well, I did get it to work, but due to another student insisting on half doing it when we started, I had to compleatly rewire it. the student insisted that we just run the high current thru the wires coming out the door for power, and use an extra switch to activate the relay windings, which is what we originally did, and I had it working using the diagrams given here. the teacher told us to rewire it compleatly in series so the door switch activated the relay. now we tried to get it, but couldn't get it, turned out we were using the wrong wire ( the color codes are diffrent between the wiring out of the door, and to the door switch ) so we just direct wired thru a fuse, and because another student hooked up the power and neg to the 2 posts of the switch, burnt it up, cooked it, so we need another switch. it was due today, the kid that originally screwed us found it more important to work on his truck. but teacher knows is all we need is a switch.
