I've just really never done anything like this before.
Actually as far as cars go, I've never really wired anything before.
Infact I just put in my indiglo gauges.
I just plugged the headlight socket straight into the car socket.
As far as I know there only a few pins in each socket...5 actually I think.
Every time I "fix" something, I end up with extra screws.
