Do the old SD ECUs have PWM fuel pump control? if not will the coyote fuel pump work without it?

Other recommendations?

thanks, that said where do you source the pump itself? I assume I will be just replacing the pump and keeping the rest of my stock assembly.

I don't believe you can get it without the assembly. You can order it off rockauto. If you want just a pump the AEM pumps are decent quality as well.
