I searched this weekend to find the wiring harness or the pig tail that would match up. No luck. Instead I purchased a 4 wire trailer hookup kit and spliced into the 4 wires. I was able to squeze crimp connectors on, secured the wires with tie wraps and then wrapped in cold shrink wrap. Turned the ignition key, heard the pump do its thing, and the guage reported my fuel level. Success!
