I don't order my stuff from overseas...it can affect warranty on a very expensive system and everything I get from esparparts.com they will support and I can be assured its covered under warranty. They also are an installer and service the heaters as well so they understand importance of having the right parts. The kits I have seen people source over seas or on ebay...are often totally different (few I have installed). For the most part I don't install a system unless I source the parts myself here in USA. I also appreciate the fact I can support a business in USA. They actually found this adapter for me as they listened to my feedback and did some searching and sent samples for me to look at.Looks like you have discovered an even better adaptor than your one in post #4. I hunted down one like in post #4 from your advice. I like the looks of these better. Had to soak the other in hot water to get it go onto the Dorman connector. It worked. Do you know why the wire harnesses are so different? I ordered mine through Heatso.com with a Easy Start Pro controller.
