glow plug relay change

So the glow plug relay in my car has worn out, the contacts that is, the relay activates, but the contacts have worn so badly they don't make the contact anymore, now the relay is oem and the wire is about eight gauge in and eight gauge out to the rail, now 8 gauge is 100amps capable, so i was wondering if anyone could give an idea as to what direction i should go, to get the relay oem i would have to look for days, lol, any links to a relay 100amp capable, i looked but didn't get any with that current rating, i know the plugs won't require 100amps of current but i want to be sure, so any opinions would be welcome.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Have you checked the fuse to confirm it is a 100 amp circuit? 100 amp relay seems quite large 8 gauge wire or not.

Last glow control circuit I worked with was fused at 60amps.

Nah it isn't quite a 100amps, it's less than that,  i have an 80 amp battery isolator from stinger i'm gonna use, since it's basically an 80amp relay inside there.

So the glow plug was fused at 75 amps surprisingly, so the eighty amp relay worked like a charm, all i have to do now is throw a 528t timer in the mix for the timing when i throw on the ignition,  i have to use a momentary button for the time being.
