I am just in the process of making a conversion harness to use the p28 (odbI) ECU in my CRX. I noticed that on my p28, there was no wire coming out of the pin locationt that is supposed to control the cooling fan. The thing that weirds me out is that there is no evidence that there was ever a wire in there! Did the '93 Civics not have a cooling fan?? Or was it controlled another way? Anyways, I put a pin in the connector and ran a wire to the pin on the OBD0 side. I hope this works, I'd like to have a functioning cooling fan when I go to OBDI.

Any insight would be extremely helpful! Thanks!

 

it is there. iam runnin a p28 on my crx right now and the fan works. one thing though, some how the ground for the fan was lost in the wiring and i had to run another one.

Cool, thanks. I have the pin and wire colour right, it was just weird that there was no wire there to begin with!
