My brother has this old Car. The Turn Signal Circuit,, Parking Light Circuit, Brake Circuit... are all Mest Up.. If I just move the wire harness,, lights turn off and on from every where!!!! I love electronics,, I created a circuit From Scratch With Circuit Maker!! I rewire from scratch, the brake, T signal, and P light circuits,,, This 3 circuits are connected to each other, and thats what makes it hard!!! On my Diagram, I will need 6 Relays, and 20 Diodees,, its pretty Crazy,, but I think it will Work!!!!

My question is,,, I been looking for a generic or standard diagram of this 3 circuits, that most of the car uses,, I just want to see how They do it.. I want to compare it to My diagram, I mean I need to use 20 diodees to make it work and 6 relays.. Where can I find a diagram of this 3 circuits and there relations to each other!!

Here is the link of the diagram I made,, What do You guys think about it??

Why do you think you need so many diodes?.. you could try the library for shop manuals to see how the manufacturer has done it...

Ok, you need to pick up a Haynes manual. It will have everything shown out real neat. I just compleatly rewired my 66 F250, and on these older cars usually the controls, relays, diodes, and switchs are fine. It is just the wiring that is dryrotted and shorted. You can go through and just change each wire one by one like I did. Another way to go about it is to find the same car, same year, in a junkyard and hope it's harness is good and just swap it in.

Looking at your diagram again. Whats up with the diodes? Why are they there? Why do you have everything connected back together after your glob of diodes? Get a Haynes manual to do it right.
