Soution for Trailer Brake Lights not working on 05 Bounder
I just solved my problem with the Fleetwood wired, RV 7 blade trailer plug to the 4 pole flat plug on my motorcycle trailer. I had initially bought and installed the standard (7 to 4) adapter, and although I had turn signals and taillights, I had no brake lights. The solution was a "taillight converter" (I bought Hoppy) that combines the separate (L&R) turn signals and brake light leads into a single wire for left (yellow) and a single wire for right (green) lead that the trailer needs for combined turn/brake functions. Since I think there are other Fleetwood/Bounder owners out there who will have this problem, here are the wire colors I found going into the 7 blade receptacle from the coach wiring:
1. Brake light lead- This was a short (6"), thick white lead coming out back side of receptacle, that was spliced onto a thinner green wire with white stripe from the coach. This one was cut, and coach end connected to the "brake light" input (red wire) on the converter.
2. Left Turn Signal wire- This was a yellow wire that was cut and the coach end was spliced to the yellow "left turn" input to the converter.
3. Right Turn Signal wire- This was a green wire that was cut and the coach end was spliced to the green "right turn" input to the converter.
Those were the only 3 wires I cut. Then I just spliced the green and yellow output wires from the converter back to the green and yellow wires that were previously cut coming out back side of the 7 blade receptacle. The Hoppy taillight converter also had a white and a brown lead going in and out of it, but those just pass through so I didn't bother with them. They can be cut off the converter for a cleaner installation.
One other thing worth noting is that the ground wire to the 7 blade receptacle was black, not white as I expected.
Hopefully this info will make life a little easier for someone out there with a Fleetwood wired 7 blade plug that needs to connect to a 4 pole trailer plug. Assuming they're wired similarly.
