k i just tried to wire it up like the diagram but i think i might have messed up somewhere cause its not working haha..
1. i got the power wire from the battery straight to the bottom relay as stated.
2. the wire goin to the top connection point of the relay is going straight to a spliced wire of the yellow and green wire off of the plug.
3. the left side of the relay is connected to the yellow and green wire i spliced but is connected to the one going to the ecu im guessing.
4. i have the ground spliced and routed from the relay to the plug and a ground spot off the chassis.
im sure i got some mistakes.. help? i sucks i wiring haha

Only cut the big yellow/green wire. The black is a signal ground, not chassis ground. I was mislead by the above diagram. Do not cut this wire.
Standard 5 pin relay: #30 - 10ga fused wire to battery, #85 - ground to chassis, #86 - ylw/grn wire from ecu (other half of cut ylw/grn wire), #87 - connects to fuel pump (other half of cut ylw/grn wire). #87a not used. Hope that helps.
