Trailer wiring harness

Does anyone have a recommendation for a good wiring harness that is plug and play? I have an MC hitch and got the harness they sell and have had nothing but problems with them. The first one shorted on the trailer side of the isolator and blew the main fuse, the brake light fuse on my bike and caused a couple of error codes. I sent that one back and got a replacement (free of charge) a few months ago. I installed it but only pulled my trailer about 5 miles and it worled the way it should. Then last night I hooked the trailer up and as soon as I hood the trailer to the bike 1 brake light and the other tail light on the trailer came on. This was with the bike switch in the off position. Not sure why these are failing but I am not interested in getting another one from MC hitch either.
Any advice is appreciated.

You might try this site:
Khrome Werks

I don't know anything about them,but the units on their site look like they would be alright.
Good luck.

I bought the Hopkins power converter for mine. Its a 4 wire but has a seperate brake wire if you want to use it. Gets its power from the battery instead of the bikes system. Easy to install and works great. I saved the 5th brake wire for when I add the extra brake light to my trailer. NAPA Part # 755-1596 About $45.00 or so.

I bought a Kuryakyn trailer wiring unit(part # 7668). It is "plug and play". It happened to have connectors for the big twins, and we replaced the two 8 pin connectors with 6 pin connectors for use on the 2007 Sportster. I found the color-use information in the instructions and was able to connect the wires into the 5 pin round trailer/bike connector. It worked right the first time (gotta love that). It uses an equalizer in the harness to allow the trailer's leds to work properly. I also added a frame ground wire to the 5th pin to insure blink-free operation.
I am also ordering a trailer hitch and this same "plug and play" harness for my 2008 Ultra. Btw, the hitch was ordered from Custom Cruiser Chrome and is a disappearing type, I can remove the tongue and ball part (no hidden meaning here) and it looks like another chrome bumper.

I eneded up sending them an e-mail and telling them I had another issue. They called me and had me send it back and said they had some others fail also and that if this one tested bad that they would send me a different kind because the company that makes the isolator wont warranty it if its used on a bike ( makes no sense to me)
So I am waiting on a new unit and will see what happens with this one. The guys at MC Hitch want to make this right which helps alot.
