Trying to figure out how to connect my heater fan to the harness. There are 2 wires from the harness, 2 on the fan, and a ground wire in the area that has one of the female and male connectors. Tthe fan and harness wires all have female spade. It is a 71 1.7. Not the best pic but you get the idea.
Help. Need heat soon. Actually just trying to get it safetied and need heat.

Can't help with the wiring, but when I got mine safetied a few years ago, my mechanic didn't require the heat hooked up, as long as the fan would blow air onto the windshield. I don't have any the fan (or any of the ducting) in the engine compartment.

the two wires from the fan itself usually green for the positive and brown for the negative, plug into the ignition wiring harness to the corresponding wires in an H connector. Positive sometimes is a yellow. if your ignition harness does not have this extra dual wire loom then you may have a 73-76 ignition harness installed on your engine

If you put a couple rubber caps and clamps, hardware store, on the J tubes you should get enough hot defrost air to pass the inspection.

Thanks. I figure may as well get it figured out while I am here but good to know I dont need to. So H connector, that makes sense. So what about the ground wire that is there with the male and female connector on it?or does that ground wire go somewhere else?

Are you saying the ground wire has both male and female connectors on it? Confused.
Nevermind. I found it. That's a piggy back connector. Allows you to plug two grounds onto one male spade. Look for the three spade ground lug at the top rear of the case where the two case halves bolt together.

My fan and harness also have two female spade connectors but they mate to a couple with two male connectors on each end - see below:

You need to tell us what year 914 you have. The early years 70-72 are different than the 73-76 cars. If you have a piggyback terminal, that is the ground for the fan and attaches to a 6mm male lug that should be on the engine fan shroud.
