Just wanted to know how big of a switch, amp wise, are you running on your setup. Id rather ask than burn a few up trying to get it right. Thanks.

If all you are doing is energizing the relay which is the way to do it, you will not need much, if you are bypassing the relay then you will need a 50A which I believe is going to cost you a fortune.
:bow:

I am bypassing the relay all together. Going from a hot 12v to the GP wire that breaks down to the individual plugs. Just putting a break (the switch) in the middle to control it.

Not adviseable but you can do it, you will need a big switch than can take high amps, and thick wires so you don't get a big drop in voltage from the battery.
Why do you bypass the relay?
It's the controler you want to bypass not the relay.
 
Keep the relay, it's not worth the hassle of bypassing it. You don't have a 12V source capable of providing the power in the cab already so you would have to run a new wire from the battery to the switch, then back from the switch to the GP's.
 
I'm sure the battery cut-off switch would work, but not like a relay is some complicated piece of equipment. Personally I wouldn't want to route battery cables with that cut-off switch into the cab, plus you need to be careful to get the cut-off turned back off before burning out the glow plugs (most people use a momentary switch). But if you want to do it that way go for it. Just make sure the wires and terminals are well protected from shorting out, and have you thought about some type of fuse or circuit breaker?
