Hi All, the AC wiring diagrams I supplied actually don't cover the ABS circuit! The best I can offer here is a copy of the Autodata info for Granada/Scorpio ('85) 2,9 24V ABS circuit, kindly supplied by Wally when I purchased Mark Kendall's car. It seems to be accurate. I will try and e-mail a pdf copy via 'My Messages' to anyone requiring it. When you locate the ABS 'ECU' (mine is located behind the glovebox), you will be confronted by a large blue 54 pin connector. Thankfully, only 25 of those pin outs are used on the Ace. The classic 'mistake' in the Ace ABS loom was to mis-connect pins 27 br & 45 bk (rear o/s sensor feed) with pins 28 br and 46 bk (rear n/s sensor feed). Basically the two rear wheels were connected the wrong way around. I recommend buzzing them through to check they are connected correctly, and change them at the connector if not. The other thing that seemed to work for me, was to get the resistances of the wheel sensors as close as possible - between 1.50 to 1.51 ohms. I had replaced a couple of the wheel sensors with new FORD GRANADA Mk3 2.9 Front 86 to 94 Kerr Nelson units from eBay, but i got pedal judder just before arriving at a standstill (along with an ABS warning light that wouldn't go out). When I'd replaced all four with matching resistances (and corrected the crossover at the ECU connector) those problems went away.
