Hi ,I have a new Alternator Wireing Harness for a 914 type 4.
Ques. Will this also fit a 912E, they have a type 4 ,right?
I figured it would be the same! Dave

Shouldn't really matter as long as the connector fits the voltage regulator. Even then you can change that. take the cover off the back of the altenator and make it how you need it with new wire.

The Alt harness connects the alternator, relay board and starter. If the 912E relay board is in the same position relative to the engine as the 914, it should work.
