What do I need to know about wiring up my '07 Heritage Softail for a trailer?

 

You'll need an isolator, a five wire to four wire converter if your trailer has four wires, and a four wire trailer connector. If you don't want to splice into the bike wires, you can use the trailer adapter from Ridetimes or elswhere.

Yea, what he said... you can get a powered converter at most any trailer supply store even uhaul sells them...

And yes the adapter from ride time is the way to go...
