suspectu1 is an unknown quantity at this point
all you really need to do in order to wire it properly is use a 30amp relay that gets power AND trigger (86 and 30 on the relay) with the IGN ON.
you then connect the 85 (which grounds the relay) to pin 104 from the ECU(pink/black). and 87 to your fuel pump +
what happens is simple: whenever the key is turned to ON, you get power to your relay that controls the fuel pump but ONLY when the ECU wants so it provides GROUND for this relay so basically this is the same way the OEM has it wired up.
