Also, Can B+ be used in lieu of D+?

Anybody know where the D+/B+ pick up point is for the ABS Hydraulic Unit. It is terminals #6 & 12. I have an open circuit between 6/12 and the battery positive terminal. My wire harness was damaged & still trying to sort it out.

Any help would be appreciated.

Thanks!!

On an 87 turbo, D+/61 is the terminal at the alternator that emits a thin 0,5 blue wire that goes directly to pin E15 in the fusebox. It forks within the fusebox and comes back out from pin D44 0,5 BL (blue) going to the alarm control unit) and pin D45 0,5 SW/GR (black w/ gray stripe) going to pin 15 on the ABS Control Unit.

B+ is another (totally seperate) terminal at the alternator that emits a thick 16,0 black cable that goes directly to terminal 30 at the starter motor. Terminal 30 at the starter is shared with a thick 35,0 cable that comes directly from the battery's + terminal.

On the HYDRAULIC equipment box, pin 6 and 12 both come out as 4,0 RED cables, which merge somewhere into a 10,0 black cable that also goes to Terminal 30 at the starter.

Finally resolved the problem. The white wire to terminal #29 was broken in the 4-pin connector. Also, had a bad diode (causing an open circuit) to the Hydraulic Control unit.

Thanks to all for their help!!!
