Going to install a 6V 3 terminal Ford Solenoid/Relay in my '74 2.0L. I've read all the many arguments for and against it, and have decided to install it.

Does anyone know the proper gauge wire for the 3 connections?? Are a #6 and 2 #10's enough?

Also, are the 2 large Ford terminals interchangeable or is 1 terminal designated from the battery and the other to the spade on the stock 914 solenoid??

I think the spade on the left is the one you want. Ohm it out to confirm. You can use a 9v batt to test on the bench. IIRC, it takes < 4V to open a Ford solenoid.
Bet you never read a complaint from someone that has one installed.

#10 from the 12v bolt on the bosch solenoid to the one big nut on the ford solenoid then #10 to a female spade, plug that into the bosch solenoid.
It doesn't matter what side you use, it's just a switch.

I use a bolt in spade on the ford solenoid little nut terminal or you can make a short adapter lead.
This way I cut no wires on the harness.

BTW I also enlarge and carefully bend one mounting tab and use the lower starter mounting stud to mount the ford solenoid. I drill no holes in the body.
If you do this you have to take care bending the tab as not to damage the bakelite body of the ford solenoid.

#10 wire - thanks.

I actually mounted the Ford solenoid to the back of the vertical engine tin after I bent out the mounting tabs a bit. The tin acts as a ground through the mounting bolts, so that works out and with both mounting holes used with nuts on the engine side of the tin, it's securely on there
