Try testing the ECU on another OBD1 Honda if you have one handy to see if that is the problem.
But, yes, OBD1 cars have ECT sensors, so there has to be a problem with the harness or ECU if you are getting that problem.
Well Däs Schmoo your first thought was correct. I finally found someone with an OBD 1 car and they let me swap ECUs, the ECU that I have in my possession worked fine with no check engine light.
I called Skunk2 to see if I could return the harness but they said I have to return it to the original vendor. When I got a hold of the original vendor they stated that they don't except returns and that I would have to return the harness to the manufacturer.
After both parties declined my request I proceeded to modify the harness. My friend and I rewired the two ECT wires on the harness. To my surprise the harness continues to throw a solid CEL for the ECT sensor. I was hoping to get this resolved so that I could send the ECU to a hondata dealer.
- And here I thought I was doing myself a favor by purchasing what I thought to be a good conversion harness.
