So I purchased a Lindsey Racing Reference/Speed sensor harness. Does anyone know what PIN number I need to solder the body ground to . The directions say the non insulated wire which I don't have. I have 3 black and 2 clear insulated wires pic shows 2 black & 3 clear. I'm assuming pin 5 . They really should put PIN numbers it would be simpler.

I just installed one of these on my 86 951. My harness came with an instruction page and all wires were labeled with their corresponding pin numbers. 4 of the 5 wires are direct plug in replacements for the wires that are pulled from the DME plug.

I'm still using my factory O2 sensor, so my remaining harness wire was plugged into pin 5 (after 1 cut and solder).

Here's the instruction sheet that came with my harness (in case you didn't get one). Between this and the instructions in the Lindsey site, I was able to figure it out. Let me know if you have any questions as the install is still pretty fresh in memory.

I got it , but my wire wasnt clear. Wish just said what pin would have been quicker
