When I bought one of my z24,s (I have 3) the previous owner chopped the wires off and had them running on a parking light wire. I found the problem in the combination switch in the steering column went bad.(an easy repair) The headlight wire diagram in the Haynes Repair Manual is accurate and simple if you understand that type of thing. Or you can get one at autozone.com just click repair info then click repair manuals.
In any handbook which shows the wiring diagram for the F350 for that year.
what part of the wiring are you looking for? autozone.com or get a repair manual,they are in the back of the book.
You can find a 1993 Chevrolet Cavalier schematic diagram, for the wiring and cooling system, at most Chevrolet dealerships. You can also find the diagram at most auto-parts stores.
Your local Library
A wiring diagram for a 1950 Ford Headlight Switch can be found in an automotive repair manual. This type of book can be purchased at many automotive parts stores.
if you use this link: http://pdftown.com/search/node/titan+headlight+wiring+diagram you will find you can download the ENTIRE 07 service manual for free. One section of this ("LT" I think) will be about headlights.
Check your local library ,they usually have repair manuals.
I'm looking for that too, if you find it, re-post anwser here! ;)
You would need to get a buddy to post the diagram on a forum. Otherwise it can't be found for free.
I would recomend buying a repair manual for your cavalier, they have wiring diagrams in the book. its not free but is useful for any future trouble you may encounter.
the relays are on the side on the drivers side beside the dash.
If it is the factory radio, then the pin-outs diagram should be stamped into the metal on the radio it-self.
