His conversion harness is $699 on his site. I'm no wiring wizard, IMO its most definately worth it to me to buy a plug n play harness that takes all the guesswork out of it. No wires to chase, no problems to track down, no need to test and retest. Just plug it in cause someone else has already figured it out for me.
I think that I may start looking more seriously at this, its a great way to keep reliability and get a bunch more power.
