Okay, I found out that my fuel pump test connector doesn't work, for some strange reason. Since I don't seem to have an access panel in my hatch, I plan on just testing the fuel pump at the MFI relay/Fuel pump relay. My question is does anybody have the wiring diagram for the MFI relay? It is a dual, along with the ECU so there are a lot of wires, and I just need the fuel pump wire.

If it turns out to be the fuel pump not getting power, I plan on running my own switch relay instead of re-wiring the pump. For security purposes and for the fact that I've noticed a lot of people have trouble with their re-wiring anyways of course. My second question is what kind of switch should I get and where?

Oh and also, I plan on replacing the MFI relay fuse on the positive terminal of course before I do anything else, but where can I get these style fuses at?

Thank you for all of the help in advance.
