Help from someone with wiring diagram for dash 700 1985

posted by  someone claiming to be slicker on  Tue Aug 13 11:07 CST 2002 [RELATED]

Hi there,
Trying to solve an intermittent problem with my instrument cluster on my '85 744 Turbo w/auto.

My speedometer and clock go out (i.e. stop functioning) on a regular basis, no pattern whatsoever. The other day, I ended up finding a loose connection on back of the cluster, re-soldered it and seemed to work for about a day. Now they just work for about 5-10 minutes during first drive of the day, but once the car warms up both stop again. Yes, I've rechecked that soldering job and it's fine, problem must be elsewhere.

It must be shared voltage or shared ground causing this problem.

Can anyone with a shop manual (or Haynes, Chiltons) identify the wires (going into the instrument panel) for the speedometer and clock?
This way I can track them from the harness into the cluster and isolate the problem(s).

Thanks in advance,
