Hello there! I have been trying to get horns and fog lights working so I can reinstall my bumper. I am seeing a lot of different information for the position of the relays, and their role. Can anyone share a diagram for a 1970 so I can determine what is used for what?

Thank you!

Not sure what year this is for, but his site has tons of useful info on it.

As I have found, the position can change based on many factors, but the function does not. You might need to trace wires or colors to find the function.

The 1970 chassis harness schematic does not indicate wire colors. You may want to review the 1971 schematic. Its should be close enough to your 1970 car, but verify.

Wiring schematics for all 914/4s on my wiring harness site, bottom of page.
