I have no idea what color wire is the hot feed but it has to come to a switch on the shifter if console .Shifter on the column it coke sout at the base. at the base .A test light will find that wire , it's not that wire but the one that becomes positive when you put it into reverse
if you get confused just run a wire to the reverse light and to the transbrake. it maybe a long way to go but it will work,

You'll need the 3 prong nuetral safety switch and pull off one the outer wires. center wire is for nuetral safety, other one is for backup lights.

Alert Alert
The backup light circuit has trouble with the current demands of some transbrake solenoids. You need to wire a relay between your backup light switch and the transbrake. Very easy to do. Instead of going to the positive side of the transbrake go to terminal 86 on the relay. Ground 85. Then run a minimum #14 wire fused 30 amps to terminal 30 on the relay. Just come off the switched lead of the relay to the transbrake. Can't remember the number on that terminal. This way the relay can handle the high current and the backup light switch only energizes the relay coil.

 the backup switch will not handle the amps of the tb solenoid.

Here you go Garth. The diode is only required if you don't want the backup lights coming on when you use the trans brake.
Hi Rick, thanks for the nice picture. Me and electrical are like oil and water so pictures really help.

The pic and brand helps. You still would be better off with a relay. You might get away with it straight wired.
We did this on a 65 Dart once. We could go into reverse and have the solenoid for about 10 seconds then it would trip the breaker. On that car the breaker is in the headlight switch. It tripped then we would hold the botton until the breaker reset itself. Finally we gave up and installed a relay.

It's strange that a relay coil would overload the circuit like that but I guess anything is possible. Here's a revised diagram with a relay. No need for the diode with this method.
Just to be clear, all three pins on the neutral safety switch are grounds. That 12v lead you show on the left, might be misleading to some.

I did this trick but ran into a very big issue. After doing burnout and popping shifter into nuetral, the trans brake would momentarally engage. You can imagine the thought of engaging reverse while still rolling forward! I found that the stock nuetral safety switch will bounce as there is very little pressure to hold switch open. It worked great not having to use button to back up but I did'nt like the idea of reverse while rolling forward.

I've got an A&A trans brake in my dart. I have it wired in direct to the reverse light wire on the neutral safety switch. Been doing this for two years, zero problems thus far.
The reverse lights do come on when Im on the trans brake. I've only seen it on video a couple of times, but I think its cooler that way. LOL
