4 pin plug at rear of Cutter

[quinault]

Hi everyone. We just purchased a 1999 Cutter DP that we love. I was wondering if someone could tell me what the square 4 pin connector, located at the back of the coach next to the 7 pin connector, is for. Is it just another version of a flat 4? Thanks

My guess would be that it's a second plug to used with a towed vehicle or trailer without a electric brakes and charge line. Try sending a picture.

That's what I was thinking. Hoping someone knew if it was on all Cutters or if it was added later. Thanks Tin Peddler.

According to the Parts Manual, there was originally only the 4 pin plug.
According to the Owners Manual, there was originally only the 4 pin plug.
It is a 4 wire round pin trailer plug, that functions like a flat 4 wire trailer plug

Going out on a limb, I'm suggesting it was a special wiring harness to provide brake and turn signals to a towed vehicle.
Perhaps power for a lube pump too?

This is 4-5 years later but I had a hard time with the turn/brake lights for the car dolly, 1997 Cutter. Did enough research to diagnose the problem and fixed the problem. Dolly lights work perfectly now. If you're interested in knowing more about the repair, contact me with a reply. I will go into more detail.
