Im fitting a electronic convertor kph - mph for my v4 type r, I've read up an found the speed signal wire and I've found a ground wire but needing a live wire, any suggestions to what wire I can take a live off of, my multimeter has packed up so struggling without it

 

I think it was Green/Black wire in the central connector. (Not the same connector you get the signal wire from)

 

Cheers ye I got it
