I've recently bought a volvo v70r with fault codes, the wiring for the abs module has been chopped and joined again so im trying to diagnose someones mistakes, the best I could find is a diagram for a xc70 and the wire colours are in the wrong placed for 3 wires, they are wires relating to my fault codes so just wanted conformation that I've found my issue, any help would be grate thanks all.

Ahh right. I might find that quite hard to find then, as it's a Japanese import.

thanks for all the information and help I'm gonna try contact a dealer to see if they could supply one for the exact car if I'm lucky.

3 wires can't be too difficult to sort out.
find the constant 12v feed with a meter.
Then ground,
the 3rd wire should be the 5v signal....don't feed 12v battery power into that wire,
use a computer safe probe, mine only allows 500milli v.
