if you have the stock harnessthe wiring in the front should be self expanatory i.e. green to green, yellow red to yellow red. i would thing the only thing not hooked up would be the headlight which is one green, one blue and one white wire. everything else should be connected. the thing you are talking about is a solenoid. I think first get a good battery and start sorting out the wiring. good luck.

Just kidding.
