'05 CC SB. Trailer is a GN '94 Featherlite 4 horse 8546.
Truck has older style 6 pin in the bed and 7 pin w/ 4 pin flat on the bumper. Trailer is a 6 pin too. Truck and trailer are new to me. I have no idea if they worked correctly before.
Running lights not working on the trailer. Stop and turn work fine. Looks like my 6 pin is wired backwards from the diagram on etrailer. Is that a Ford thing?
Running light position (top) doesn't seem to have power with the lights on. Checked fuses, but didn't see one specific to trailer running lights.
Also, the brakes didn't feel like they were working. I have the factory onboard controller built into the dash. Tried testing the output at the truck side in the bed, but to no avail? I read that the early '05's (before 3/23/05) have a different output voltage than the later ones. Will this make a difference with the trailer brakes?
Thinking of just converting the bed to the newer style 7 pin and trailer too. Would like to have trailer battery(s) charging while driving. Not sure if I want to mess with adapting the trailer end... The other option is to run a pigtail from the 7 pin on the bumper to the batteries with a separate harness to charge the batts - they are close to the bumper when hitched.
Plan on working on it today once daylight arrives, so any help is appreciated.
Running light thoughts?
Brake testing thoughts?
Changing to 7 pin thoughts?
