I ride a 2001 HD Ultra Classic and it has a 6 pin rectangle plug wiring harness. I recently bought a tag-a-long trailer that has a 4 pin flat plug. Is there an adapter to allow there two plugs to connect?
I have a similar problem.
One of my bikes has the five wire flat connector, while the other has a six wire rectangular one.
My tow along trailer, has a five wire flat as well.
Do they make adaptors for six wire rectangular plugs, into five wire flat tariler side plugs?
