Car: 87 TII

Problem: Need to know which wire coming out of the ecu is o2 sensor wire, color and location would be awesome. Looked at wiring diagram, it did nothing but look back at me. Harness sold to me has lots of chopped wires, but 02 is not easiliy noticeable, will have to follow ecu forward.

Owner: is a dumbass

Pin 2D as shown in the wiring diagrams downloaded from this site.

Yeah I got that, but I dont know which is pin 2d. Does that mean if I'm looking at it its the second pin on the bottom from the left?

Like the wiring diagrams say..............You look into the wire side of the plug. You count in an up/down fashion from the far right side of the plug.

Pin 2D is in the middle plug...........bottom row.............second from the far right on that bottom row. Should be black.

IF you follow that black wire up the harness a foot or so , it becomes apparent that it is a center conductor of a shielded cable. The cable itself is grey. The center conductor is black.

I posted a picture of the cable as it enters the cabin at this site: https://www.rx7club.com/forum/showth...highlight=grey
