My wiring for my e valve got damaged from heat and made the e valve not operational. Called RPM and the directed me what to order and how to order it. The harness arrived in short order and worked perfectly. I would buy all my stuff from these guys if I could because they are so good at what they do. Unfortunately they don't carry everything I want but I can't expect the same quality and service from other companies. So far nobody is as good as these guys.
