powerglide with transbrake question

[Johnc]

How should I wire up reverse lights? Should I use a relay and connect it to the momentary button for the transbrake?

Yes.

[Johnc]

Yes.

thanks!

Just for clarity - the reverse lights should go on the output side of the relay, not the side you're switching.

So, your switch should be 85/86 and power should come in on 87, with the load (transbrake and reverse lights) on 30.
