You talking about the light not working or the ABS system?
I installed the entire system, brake master, ecu, harness, sensors, lower arms and front hubs with correct tone wheels from a Sapphire 2wd Cosworth, into a Merkur XR4Ti that didn't have ABS. The system is working, hit a wet spot under hard braking and felt the front circuit being activated. Just would like to wire up the warning lamp properly. Got a Sapphire cluster that I could interchange cluster panels to use its bulb socket but would like to connect the one above in pic to warn me. If I can find out the proper circuit for the light I'm good.
