FD ECU Harness Connector
Hey guy, I have a 93 Automatic FD and have finished doing a rebuild but when wiring up the ECU I found this connector and have no idea where it goes. If anyone knows where it connects that'd be great Thank you!
That looks like the ground used for diagnostics. It is normally unused and not connected to anything. Way back in the day we used it for the “fan mod”. It caused the fans to run for 10 minutes after shut down in an effort to reduce underhood heat. But it was never effective. Leave it.
