I painstakingly pulled this harness from a parts car I had. It runs from the ECU under the passenger seat, to the column, through the firewall to connect to the engine harness and also includes battery cables. This harness includes the resistor box for the injectors, the radio harness and fuse panel as well. 

It does NOT contain the actual smaller engine harness that plugs into the fuel injectors, alternator, oil pressure switch, etc. 

This came from a running 1986 CRX SI with the fuel injected PGM-FI 1.5L EW4 engine. 

There is one place where I had to cut the harness, and I don't remember what part of the harness it is. You can see it in the third and fourth pictures. 

I also have a matching ECU that I will also list separately. 

Let me know if you have any questions.
