All types. Mostly 1970's and 80's F-series pickups with certain options. Aux battery, Trailer and Camper specials, all had safety relays.

They can be bought aftermarket as well. Which is what I would do.

They can be rated anywhere between 10 amps and 100 amps. But am not sure which are rated which.

Mine is only 40 amps, but I am only using it to control other relays for lights and other add ons.

Contactors are bigger "relays" where usually a block of contacts move together. A relay is usually a set of spring contacts that warp to make contact. Anyway, here's a pic of the solution for me, once I find a place to mount it. One relay each for high beam, low beam, l. turn. r. turn, 4way, and running lights. All fed from a 30 Amp upfitter switch. (By the way, the upfitter switch relay panel has a ground wire that can be switched to disable all the upfitter switches at the same time).

I wired my off road lamps into through a relay that's triggered with the high beams. My off road lamps are 150 watts.when my high beams are on I can flip a switch and turn them on,and when I dim my lights they go off automaticly.
