Wiring 3rd Brake Light for Trailer

Jul 04, 2007 3 Replies

I'm using a 4-pin plug to power my trailer (1972 Serro Scotty Gaucho) and having trouble wiring the center brake light. Is there a way to make this light brighten with the brakes but not blink with turn signals? I have the standard 4-pin connector:



brown: runner (tail) yellow: turn signal green: turn signal white: ground



Any advice is appreciated, john



nope. the yellow and green are actually combined brake lights/turn signals. There may be a converter box made for this application but I am not sure, and I don't particularly like them (had to cut a smoked one out of a friend's truck as it was causing all sorts of electrical wierdness.)

Trailer converters are often very poorly made, but then again so are most connectors. Example from experience: Toyota has spec-ed a bunch of crap converters for their OEM wiring kits. The stuff is far from usual Toyota quality. Damn near 100% of their standard equipment electronics are bulletproof, but some of the port/dealer installed alarm modules, trailer stuff, etc. is no better than typical Directed Electronics crap.

there is no requirement for a center brake light. there is a requirement for 3 rear red marker lights on trailers over 80 inches wide.
