Trial and error?

What is a "connector switch"? if auto-uncorrect changed selector switch, then my HD FNR has same studs as stock. ALL studs on mine are the same, except the super duty solenoid. I can't speak to the reversing contactor. I'm satisfied with mine - SD solenoid - but a reversing contactor can definitely take a lot more, and should probably hold up longer, while still maintaining reliability.

From Scotty B's web site https://www.cartsunlimited.net/rever...ontactors.html Heavy Duty for 3-400 amp controllers (use with standard 5/16 cable lugs)
Super Duty for use with 500 amps & up (4 bigger 3/8ths cable lugs required)

My HD FNR was a few years ago, so always good to check, if you go that route.
