Is anyone making a flat five wiring harness? THe burb i just bought has a round plug on it (which i personally hate), and only tow boat trailers that have flat 4 /5 connectors on them. I can buy a flat 5 plug and wire it myself, but does anyone make a harness? If not, i'll probably just get the uhaul one again ( i like their bracket/cap). FYI, flat 5's are often used for surge brakes with electronic reverse lockout solenoids hooked up to the brake lights.
