I agree that it would work if you remove and rewire the plug so the wiring to the later switch is correct. But that is a change to the factory harness. Lol No change to the actual wiring harness. Just remove the brass terminals from plastic and reinsert into replacement plastic holders. No need to cut/crimp wiring. Easy to understand: you're just replacing the earlier 2 plastics with the later 1 piece. Doesn't require a degree in electrical engineering. The earlier switch is larger cause it has a rheostat built into it.

Thanks for the diaphragm, but if I am understanding this correctly, you will have to either put all these wires into individual plastic insulators or have a complete one from a 72 up wiring harness and just move all the wires? I think this would have been way over my customers head so I opted for the modified and rebuilt variable speed switch from Devinism for a little over $200 and it just plugged right into the customers new 70 harness..

Yes, you understand correctly. You made a good call going the K.I.S.S. method with consideration for your customer's skill level.

I think I will try to find either a 70-71 E or 67-69 A switch. I am not going to mess with the wires either. ???? It's as simple as removing a terminal front 1st plug & reinserting into the 2nd. Repeat until all are done. Never understood how many are so hesitant to do even some simple wiring tasks on a 12volt system. Now newer cars I can understand, but these older systems are simple in comparison.

Just call up Devinism and he can fix you up with a restored switch that will fit your 70 harness and plug.
