For that you can get a regular Chevy van (p30) manual at Auto zone etc..like the Chilton service manuals. The lights wiring should only go from the lights to the switch on the dash with power entering the other side of the switch! Other than that ts the grond which is a short piece of wire or the light fixture itself going to a very local ground point! If you don't know how to use a multimeter you should get a little lght tester... turn on the lights and see how far the test light stays on from one point to another,, when it no longer lites up,, look in that area far the open or dirty connection. |
