I just removed the wiring harness from my '75. I am not sure what the PO did or what happened but there are a lot of shorts with melted and exposed wiring. The seat wiring is melted into a large uniform mess.

I hate any form of lock out with seat belts. Can I remove the wiring and sensors or is there any reason I should restore the wiring under the seats and then make the modification to delete the lock out and fasten seat belt signals? I can't imagine a future owner thinking they would want to have the wiring available to connect a starter lock out to the seat belts.

Dave, that photo above looks odd somehow. A Euro or Canadian amrket car or perhaps a one off customization? As far as I know the interlock system was only a USA legal requirement, and the single relay solutuion seems to be just a door buzzer indicator not an ignition lockout.

Not sure how specifically that it is different other than it does not have the double sized base and small cube (which I still think is a buzzer. It may be a power relay technically but it also buzzes) and the single logic box base connector is unlike any I have seen. I have over a dozen 74-76 chassis harnesses in my shop right now and none look like that. That base only has one screw and the logic box looks atypical to the USA cars. The euro cars did not have the seatbelt interlcok system as I understand, could these be euro market cars you have? The 74-76 USA cars do not have the round buzzer on the fuse panel like the 70-73 cars.

I assume you have seen my diagram of the wiring also attached. Thats all I have at the moment without further review.
