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.

No, that is really great info. I just came in from tinkering with it. When I jumped 10 & 11 I used a very small jumper. Duh. I heard the fan motor dragging and saw smoke from the "small" jumper which couldn't handle the load. The plug doe not have pins in those 2 spots so I'm going to need 2 pins so I can make a jumper, I think. I say I think because I haven't jumped this with a large enough gage wire. So, those two wires with the blue tape would have plugged onto the coil if in an earlier version? They're certainly the right length to connect there as well.

You make a jumper wire out of the 2 extra blower wires in your engine harness. Pop the cover off the 12 pin connector and find the 2 extra wires pull enough of the green wire to cut it about 1 1/2 inch or so from the pin connector. Pull the brown wire out enough to heat the solder at the pin connector and remove the wire from the pin connector then solder the pin connector onto the short green wire you just cut. Now you have a 1" jumper you can bend into a "u" shape and put 1 end on pin 10 and the other on pin 11 and put the cap back on the connector. I would pull both wires out of the engine harness completely but you don't have to, just make sure they can't short to any hot wires.

The green wire would not have been connected to the coil, they would have plugged onto the blower motor mounted to the engine. The coil gets it's power from pin 7 on the 12 pin connector via a black/red or all black wire.
