I have been wondering for years if my PC3 was wired correctly. This is a black box (seen in photos) about 2"x4" in front of the PC that has wires in a black sleeve that are at least a foot longer than they need to be, so I am wondering if this is an add-on. Despite some odd looking wiring I have never had a problem with the bike, but I would really like to know if everything looks okay, or if I should do something. Let me know what you guys think.

This is the little black box.



This is the really long cord coming out of the black box:



This white plug is what the black box plugs into:



This green plug near the battery is not connected:






This is the PC3. The cord coming out of it goes up the left side of the bike and plugs in near the front of the motor. When I turn the bike on a light comes on.



This white plug near the tail lights is connected to a wire that is cut, and has electrical tape covering it:

It looks like the black box is a speedo healer. Have no Idea if your PC3 is connected correctly to the injectors or not. I think that white connector is your license plate light.

as stated before

the mystery black box is a speedo healer. it's plugged in line with the speed pickup. the white plugs are the stock connectors, the green ones to to the healer

the green plug with nothing plugged in by the battery is the service connector. this is normal


the PC plugs in line with the throttle body connector, it's nearly impossible to mess up. make sure the black wire with a ring terminal in the PC harness is connected to battery negative.


the white plug at the rear of the bike is the license plate light connector. it looks like you have an after market setup so they probably just used the positive from the bike and a common negative. hence the use of only a single wire



any other questions?

Thanks for the info! The. The black PC wire is connected to the negative terminal. Looks like everything was done properly.
