Anyone know where I can find the circuit diagram for the wiring underneath the steering wheel?

I want to hook up my Valentine one using the vampire clip, but don't know what wire to tap to, since I don't know what they are.

I have the electronic version of the maintenance manual, but don't know which section it's in.

 

You don't need all that. All you can do is get in line fuse and use cigarette lighter fuse to splice which is switched power.the fuse box is under the panel by your left knee.cigarette lighter fuse is second row from the top and 3rd from the left 15A.and find the good ground of course.gl

 

Use an add-a-fuse on the fuse box. tap it into the gauge cluster as that's switched power when the key is turned
