Re: can someone tell me what these switches are
I do think the one on right is a breaker and the one on the left is a relay....
glad it's not stock....wires were wrapped up with harness and almost looks stock, and been there a long time. |

Re: can someone tell me what these switches are
They are not stock. Could be for aftermarket horns, trailer brakes, a/c, etc...I don't think you will need them. Joseph

Re: can someone tell me what these switches are
Those are part of the TCS (transmission controlled spark) system.

I had them on my '72. I removed them when I took the spark knock BS off the truck.
