Ok, I have an extra fuel pump relay off the old truck that I might be able to use as a relay for the Holley fuel pump (switched by the fuel pump lead from the Painless harness). Does anyone know that the connections for this relay are? It has a diagram on the top that looks something like this:

There is no "C" connection, only A, D, E, and F. I do know that if I hook D to my + and a test light (from -) to F the relay will click and I get a light, but that doesn't seem right...

Thanks.

Looks to me like D is battery + (painless fuel pump lead) F is battery -. When power is applied to D the contacts are closed E to A.

Test it by wiring E to battery +, test light between A and F and wire from F to bat –. Light should be off, connect D to battery +, light should go on.

Exactly right! Thanks!

Here is one way to do it
