Hello I'm Reggie the reason you can't find the relay is becauee it is internal to the power distribution center, the plan is for you to buy a new power distribution center, thats the proper way. Personally, I purchase a relay and wire it in. The dark green and black wire that powers up your pump u can find that coming out of the pdc

do I need to ground the pump also? What wire would u use

The pump already has a ground. If you are wanting to add a relay you will need an accessory relay thr pigtail to it an inline fuse holder and 20 a fuse. The relay will have 4 terminals each will have a number 85 86. 87. 30. This is how you wire it 30 hook that to the power wire going to your pump 87 rum that to your inline fuse holder and from there direct to the battery you can also make a jumper and hook that same battery supply to 85. 86 we will hook that wire to the wire that the pcm uses to command fuel pump on give me a min I have to look th at up
