Abs/traction light on and brakes affected

the very last thing to replace would be the abs module if no wiring issues are found

Where to find this revised harness?

i would imagine a pontiac dealer if you can find one. Could always try a gm dealer

'02 right?

I know that this thread is a couple of months old, but I would like to know where to take my car to have it "scanned". A stealership or would I just have to call around and ask? Replaced both front axles and hubs and the lights still keep coming on. I'm thinking that it may be the wiring - the scan will tell me exactly which side wiring is bad?
