Stop in for a cup of coffee

Did a little research...
From 75 FSM. Here are the wires going through grommets. What is really strange - in 74 book the blower and compressor switch are same as pictured here, but the oil and temp go through the bulkhead. Then in 75 they take 2 wires out of the bulkhead and through a grommet. In 76 FSM, they are all in the bulkhead connector.

I can understand running a grommet for the A/C option. No idea why the sending units for the gages would get a grommet. Funny the wires on your car don't look like violet and green. Well maybe violet - the other looks white. LOL.

Talk about things not done same as shown in the book. Did you see this on my car?

Hole with cap plug is factory location for the antenea wire.

Drilled through the kick panel too.
Best I can tell this is factory original. :realcrazy:

I have no idea what happened.

Maybe the car got to far down the line before somebody noticed the cable wasn't installed. Instead of pulling it off the line to correct they just drilled through????
Classic!
