Yes positive, you’ll see from the photo above I extended the black cable so the crocodile clip could reach the boot. (Note that yahoo were closing the group for KWP back in October ). I think they don’t want to support free groups any more.Hi Tony,
I bought the correct cables from scantool,part #kkl316. The three pin cable has a red wire with a crocodile clip. Am I correct that this must be connected to the positive of the car battery ? I previously assumed there would be a negative connection on this cable,so the negative connection must be one of the three pins ?
