ok, I looked over the existing circuitry that was on the car and I drew it out the best I am able to.  I attached the file and labeled what I could.  I have no idea what the transistors are or if they are NPN or PNP, but I labeled which ones are the TO 220 cases.  Maybe that can help get me a little farther on what I trying to do.  I am redoing this circuitry so I can control it when I want to....it is just being a pain :p  I know alot of members on here know way more than I do on electronic design so hopefully someone can decipher through my wonderful schematic.

I am also looking into the H-Bridge MOSFET circuits and am finding that it will be more trouble than it is worth since I need to control the positive side of the solenoid which causes more heat since the P channels are slower reacting.
