Reverse light switch - TR6060/LS3 swap
Good Morning All,
I am going over the wiring for my '73 LS3/TR6060 swap and want to confirm the wiring for the reverse light switch. I can just wire that into the existing pink/green wire circuit correct? The switch/plug on the passenger side of the TR6060 is open when not in reverse and closed when in reverse? Also, the ECM does not need the signal from the reverse switch, correct?
Let me know if I have this wrong.
Thanks,
Scott

I have not verified 100% but from what I can see it works just like the original reverse switch, it is closed in reverse, otherwise it is open. I made a new pigtail (with the brown/green wires like the original!) but with the plug for the TR6060 to plug it into the existing harness.

I don't think the ECU needs to know the engine is in reverse, but it does want the brake signal. As you eluded to I reversed the brake light signal with a relay so that the ECU sees 12v normally and 0 when the brakes are on. The circuit to the reverse is just a switch that is closed when the transmission is in reverse, otherwise it is open, so it can be in the circuit to the reverse lights. I my response above I said it was brown/green wires, but it is in fact a pink/green pigtail.
