Guys trying to get this Hella SSR working for fuel pump control. No matter how I hook it up it runs the pump. I apply the MS3X control signal and ground on the on the control pins and it stays running. I also tried the MS3X signal and positve on the control pins and it still just keeps the pump running. The pump stays on all the time no matter what. Any thoughts anyone else run into these issues?
Thanks

Post a sketch of the circuit. That will avoid a lot of questions.

I tried everyway possible to hook it up. Just sent it back and got a Dorman 902-310 and it works perfect plus it handles 40 amps.
