DME harness pin diagram
 

I have been working on a 1986 911 targa trying to bring her back to factory wiring.

two questions I am asking help with.

1. Is there a diagram/picture of the DME harness which show what each pin serve. (Need to tone and ID speed/refrence sensor to agree one from the other) Also would like to check each lead to their sensor/ signal/load.

2. On the 911 DME harness, there are three empty slots. Counting in secquence 1-18 and 19-35 slots 30, 31, 32. is empty. Are they omited by factory design ?.

Thanks

John

Pins 30-32 and not connected to anything in the Carrera. Inside the DME, pins 31 and 32 have no connection, while pin 30 is an analog (sensor) input t0hat in unused in the 911. The same basic DME unit was used in 944s and BMW 3 series at the time, so may have been used by one of those.
