Hi,
another question from my ongoing rewire dilemma.

The plugs were ripped off the ends of the speedo healer so need to know which way round they go. It is on 97 blackbird.

I have an end with red-black-white and the other with red-white-blue. Assuming the red and black are + and ground, which way round are the blue or white for signal in and out?? Not sure which V.? the speedo healer is but it is not a V4 as sold nowadays and has no top speed button. so maybe v3 or V2.

many thanks

Pif
