My DOC's ESC install.

After searching for a electrical problem on my K9 my ECH started smoking I decided to go with a new ESC unit.

I first pulled out the screwed up BD wiring harness and controller.

Installed the ESC unit in the same location as stock ECH. Plugged all connectors with dielectric grease and sealed with liquid tape. All wires with the new harness are lettered. A complete full colored wire diagram show what function each plug goes to, very simple.

Ran main harness through the backbone and plugged in all branch circuit connections with a dab of dielectric grease. I then sealed all connections with liquid tape. The ESC comes with a completely new braided steel headlight wire with ceramic plug. It gets rid of that three feet of coiled up wire in the 08 K9 headlight bucket.

Used the included zip ties to bundle up the wire harness.

Zip tied the backbone harness and wrapped it up in the under tank cover on the backbone.

And done, all stock functions work perfect. I did go with the electrical system monitor also. I haven't even had the dreaded starter clunk since.

Let me know once you had it out a couple times if the starter clunk Is gone for sure, I had it happen about 8 times in 5 days in Daytona:old2:

Nice work, BTW does this kit include harness for the rear and front run/turn signals. How about the hand control harness do you have to use the same one that came with the bike. Just wondering, cause of the size of the stock wires that came with the BDM suck.

No, none of the replacement controllers come with any of those harnesses! I thought the same thing when I was installing my ESC, but at least the DOC's comes with the one that you must have! The headlight harness and ceramic plug!:old2:

So far I have not had the starter clunk, past three days been riding a lot. Everything is working great, bike is running better then ever. The end is here though, I will probably be putting the K9 away this weekend.

I still catch myself turning the throttle when pushing the start button once in a while. Bad habit from my old Harley days. When not touching the throttle the engine turns over very fast and smooth.
I used to do the same and I started awhile ago just using my index finger to push the buttons without my hand on the throttle, I think its one of those natural instincts, if it don't start, give it gas:oldhardlaugh:
