Default LED light bar blowing fuses

I just wired a 20 inch light bar onto my brush gaurd and it blows the fuse as soon as I hit the switch. It's a 120 Watt bar and I'm using a 5 pin relay, a 3 pole switch, 10 gauge wire into the relay, leftover 16 gauge wire from the relay to the switch, and a 30 Amp in line fuse off the positive terminal of the battery. I don't know much about wiring and it didn't come with any instructions or diagrams. Any help is appreciated.

Well a 120 Watt bar shouldn't be blowing a 30 amp fuse in normal operation, I would guess a bad ground.

Has to be a short somewhere. Check all 12V cables make sure they are not touching ground. Could be a bad switch or maybe a bad relay.

Absolutely a short/ground. Do you own a meter ?
