I wanted to change this wiring harness today but the temp is 16F and colddddd. I'll take some pictures, but this is really easy. This harness connects at the top of the computer housing on the passengerside and the rest of the connections are very easy to follow. Replacing the main engine harness was actually a snap too, about 2 hrs or less and it was made easy by some pictures that were sent to me showing how to access the firewall pass through for the main connection and some tips on removing the wire connections from the injectors. I wish that there was a better service manual available for this vehicle, with better pictures and illustrations. My MGB, MG-TD and TR-6 and MIATA manuals were great compared to what I've had to work with.
