Just picked up a pretty straight '88 5 speed (been 5-6 years since I had my last bird, woot). At any rate the ABS light is on, pulled the codes and came up with 21 (main valve). I checked the resistance of the main valve connector and it reads out at 5.6-5.7 ohms. In the book it says anything above 5.5 needs to be replaced. The pigtail was a little tight but seemed ok. Is there anything else I can try, short of swapping the ABS actuator assembly out/ignoring it?
