6 pin trailer connector wiring diagram drivers#
Dim brake and signal lights in the daytime highly increase accident risk because ALL drivers are accustomed (per-disposed) to react to bright turn and stop signal lights. Because the diodes are there in the convertor, toad side brake voltage is automatically 0.7 to 0.9 Vdc lower than on the coach side of the connector, which if you have a weak flasher or poor contacts in an automotive brake relay, may already be at 11.0 Vdc, maybe even 10.0 Vdc or less.ĭon't drive at night so dim lights are not a problem?Įven dim lights are generally detectable in the dark, but dim lights in the day time all but disappear from detection.For example, if those diodes weren't there in the convertor, every time you put a left or right turn signal on, all of the coach brake light filaments would flash.brake and turn use one common filament on the toad side but separate filaments (bulbs even) on the coach side, etc.UNPOWERED convertors use diodes to prevent the backfeed of "commoned-up" wire voltages on the toad side from feeding back to the separated wires on the coach side.Increased wire length/additional friction fit connections lead to an increase in the overall wire resistance which drops more voltage which leaves less voltage to light the lamp filaments (perhaps even enough voltage drop that if the Toad brake or stop lights are LED, the LED won't even turn on, which typically happens at around 9 Vdc decreasing).
When one converts the Foretravel 6 wire lighting convention to a 4 wire Toad (car or trailer), in order to be safe, one must use a POWERED convertor, or the Toad turn and brake (and emergency flasher) lights will be dimmer than normal. So I installed a powered converter like this one Curt Circuit Protected Powered Converter w/ SMT Curt Custom Fit Vehicle Wiring. I had the converter just like your pictured napa device and it failed recently. An electric brake pin is variable voltage and would be used by a controller. This might be up for interpretation because I see diagrams that refer to this pin as brake and I find other guides that refer to it as electric bra1ke. The brake connector is to be used for an electric brake. The Foretravel (mine at least) is not a properly wired 6 way plug. My bet is that the tail light converter is cutting power to the running light filament while the braking filament is lit which probably isn't right. The parking/brake lights are a little close in brightness but it gets the job done for now since we don't often drive at night at all. My solution to the problem was to wire this in NAPA 755-1086 tail light converter NAPA AUTO PARTS which will handle combining the split signal/brake wiring from the foretravel into my "US style" wiring. While some day I could run the additional brake light line back and change the brake lights to the signal lights to flash, I didn't want to mess with that today just before departing on a cross country trip. As such the Lexus has only left turn, right turn, tail and ground running through the chassis to the rear. While my Lexus GX470 toad has amber signals and red brake/running combo lights, the previous Winnebago I had it hooked up to had the US standard combo red brake/signal lights. Joeszeidel, you might be missing the problem.
