I have the dreaded anti-lock light on all the time. I looked at the relay, which is a Bosch. Is this an original part? When I checked the Bosch web-site, I could not find the part. I was able to find a listed AC Delco part at discountparts.com for $27.
There are four wires going to the relay. The black one, the ground, as expected was 0 volts. The orange-black and the pink-black wires had 11.7 volts. The orange wire was zero. I think the orange should also be hot. Is it the relay? I don't want to order a new relay if I don't have to.
