new harness is in, KEBC pos. works again but the 4wd does not. also had to swap relays. the bike would only start with the brake on. I was not able to hook my fan up the same way. had to splice into the blue fan wire and then ran some red speaker wire to the bat. toggle works fine now. sounds stupid but the fan is way faster...i noticed a huge difference. 4wd is still flashing, and the actuator is making a noise like steel on steel grinding when moving. not good. guess it will either be an actuator or controller. not sure , both expensive. I have used Toyota relays in the past but forget the part numbers, wonder if anyone here would know. the wires were easy. took bout an hour and 1/2 left back clip on...saved the dealers$400.00 tear down and install price. how do they sleep?!!! also gonna pull the actuator again and add 12 volts. any tips on install will be greatly appreciated.
