    Does anyone have an airhead (/6) wiring diagram for Acewell or Trail Tech (Vapor) speedo?

    if the bike has an electronic tach the signal wire is black coming of the coil. the other black wire is coil trigger. but I would go to the aftermarket tach diagram and work backwards, if that is any help. if you do not have an electronic tach you will need a sender.

    Edit: for some reason I thought you were talking tachs. if I am correct, there were no electronic speedos. so the only wiring is the light.

    74C1E69A-20D4-4EDA-9A20-CDD00B1C4068.jpeg I put an ace well on mine, just followed the wiring diagram as supplied and checked against the stock one. Can’t say I had any issues at all. That was on an acewell....
