its a round with a 7-pin to 4-flat. But it blew on my Mom and Dads H3 with their own plug as well. No swing tongue but the wires are old.
Bad ground will not blow a fuse UNLESS it is touching a hot to lights which would make you have a bad hotwire also. Like they said, I'd just rewire it.Buy a 50ft extension cord and use it in halves to run to both sides. You have running, brake/turn, and ground all in a durable sheath.
I ran my new wires through a piece of rubber hose for the last few feet toward the tongue end to keep vibration from vibrating through, or a hard tug from compromising the wire and causing problems later on. Might be overkill but it's a cheap insurance policy.
