Where can I find a O2 (Lambda) harness?
 

I converted from a 77 2.7 to a 80 3.0 . The new engine has a lambda (O2) control box that goes under the drivers seat. I need the cable that connects to it and runs back to the engine compartment.

This is NOT the (DME Brain) cable for 81 and up cars. Or if someone can tell me how to make one , that would be fine also. I have looked at the prints for the wiring, but there is no numbers on the pins on the control box.

Thanks
Rick

These are the part numbers I could find for the Lambda harness and O2 sensor.

Oxygen sensor -- 928 606 123 01
counter switch harness -- 911 612 149 01
counter switch -- 911 641 225 02
warning light OX2 -- 477 919 209 B

I did not include the Lambda unit since you said you had one in your post.
