'83 Euro 3.0 into '78 US, Wiring Question

[911SauCy]

I'm sure someone will be able to help with an answer to this.

I've reviewed some wiring diagrams but am still unsure, likely due to the different years of the car vs. motor.

Trying to determine what the below pictured, goes to/or is for? I've accounted for where the other connections are made and I'm thinking this one might go un-used...?

Looks like there is a model year translation from the '78, which has a 3-pronged connection for the voltage regulator. There is nothing on the '78 body that will accept this.

Please advise

Engine Blower motor connector. ‘78 was a flat clear plastic connector.

83 has a built in regulator.

That’s heater motor plug

+1. Just tuck that three prong female connector out of sight.

On the '83, I don't have a female 3-prong.

However, I do have another 2-prong female like this, with a white connector instead of black, also in a T-formation

Do you have the targa window heater element accounted for?

[timmy2]

White connector is for the CDI power and air flow safety switch wires.
There should be a white 2 pole connector near the 6 pin CDI that it plugs into.

The yellow/black wire and brown wire in the black connector are for the blower motor.

Lol, I just finished building a new '78 engine harness for someone 10 minutes ago.
Feel free to PM me your phone number and I will try to answer any questions you have.

I gotta say this is a pretty sweet offer.

^^ No kidding! Timmy2, I will be sure to take you up on your offer if I have further questions.

However, you solved my mystery to this point

THANK YOU
