Im putting Ford based EFI on my 65 Comet, and Im about done except that Im not sure where to put the ECM. Ive done some looking online and at my car and there doesnt seem to be a good open spot of real estate. Im using an extra long Painless harness and I think there are some very minor differences from a Ford harness, for whatever thats worth. I think what Ill do is drill a hole in the firewall for the harness about in the car centerline, just above the base of the intake, but again, the harness is long enough that I could put the computer under the back seat if I wanted. I just cant seem to see a good spot to mount the computer. So where have you Falcon/Comet/Fairlane/Mustang/Maverick guys mounted your ECM? Pictures please!
