this literally cost a 10th of getting matched part from Dodge dealer
We had to disassemble the wiring plug, and reuse the original from the old part, in order to get it to plug into the truck wiring harness, but for a few hundred bucks less than getting it from Dodge, that is O.K. It's been a couple of weeks, and so far it's working fine. Great value for the money.

Does not fit p7100
Absolutely does not fit on a p7100 pump. Binds up and does not operate as it should. Caused me plenty of headache and had to buy another. Do not recommend.

Bad selenoid
Horrible product. Did not work properly. Turns truck on but will not stop. Adjusted it and still no go. Seems like these electronics from China are have no quality control.
