Wiring Harness Question, What is this? Options

[76-914]

What do these go to. This car is a '73 which was originally a 1.7. I thought it was for the blower but it's not. It's the green and brown wires w/ the blue tape and comes off the small black harness that the coil wires come out of also.


Another shot showing the black harness from whence it comes.

Early cars ('70-'72) had the blower wires in the engine harness, and they were green and brown. That looks like what you have. Easy enough to take the cap off the engine harness plug and look where they go, or just use an ohm meter. Once you know which pins they go to, looking at a wiring diagram is gonna provide the answer.

If you look at the relay board diagrams on the bird board, you can see the difference in the blower motor wire routing.

Early cars have it routed through the relay board to the rear connector and into the engine harness, later cars have it exit out the body harness just under relay board.

You have an early engine harness. If your main body harness is of a later date, be careful as the layout of the pins on the rear connector on the relay board changed somewhere in late '72 (if i recall correctly). You can use the early engine harness but i would double check all connections on the plug to the relay board to make sure they are on the correct pins.
