Turn stop tail wiring

Ok, what is the best method for the turn to override brake on a 3 wire setup.

One wire high power, one wire low power, and one ground.

I have heard of a 4 to 3 convertor, is that a thing? Do they last?

Thanks!

Had a 4-3 converter for a trailer at the camp, just after the Millenium.

It was deployed according to the vehicle that was designated each summer, depending on what it showed up with for lighting.

Worked great.

Reese has been in the game for a long time.

Consider changing any single filament sockets back there to dual filament ones and deal with it that way, without going to another electronic component.

Everything is led, ended up getting a 4-3


On another note, what is the brake switch cut in psi supposed to be?


Thanks

Another thing to consider is possible voltage difference with the bus being 24v and the trailer 12V. Previous owner of my bus complained that it cost him $400.00 to put in a converter, where he could have probably gotten by; by converting the trailer to LED lights.

True Fred, but eagles are 12v, and my rear turn stop tail lights are led 3 wire.

For a trailer I can just pull straight off of the rear lights.

The crack pressure of the brake relay is like 2 lbs. A switch with the same activation pressure will work. Go to Bendix and get the correct answer not from some old wore out mind.

I haven't had the best luck with the converters. They just go bad on me. I am actually in the process of adding separate amber turn signals inside my reverse light housings on my Ford Expedition to remedy the issues. I'm sure there are easier better ways but it's my way. I just think ambers are more visible in a sea of red tail lights anyway.

Thanks Wayne.

Scott, I am going a little overboard on lights on the back of the bus...lol

I guess I'll have to take the chance on the converter going bad, if it does I guess I can assemble a conglomeration of relays and diodes to do the job.
