I would like to put my fuel pump relay in the trunk with my battery and starter solenoid. Having never done an LS swap before, I'm not sure where to start with looking for a relay/harness. Can someone recommend a relay and a harness (I assume I need a harness for the relay to plug in to)? It looks like the relays with the PSI conversion harnesses are intended to be mounted in the block with all the fuses near the engine.

I used this kit and it worked really well.

Sweet! Thanks for the link! I'll take a look at that and see if I can find the instructions online so I can figure out where and how much space I'd need to mount it.

I ran the wire from my driver side mounted truck alternator, through the firewall, through the cabin, into the trunk and out the taillight harness gasket, I just attached mine to the bumper behind the cover. The Relay is about the size of a post it note.

It's on the way. Now I'll be able to sort out mounting my solenoid and my relay at the same time.
Thanks for the help!

One thing that I did for my install was use a very thick gauge wire from the relay to my pump (10 i think) and a very beefy 3 pin quick watertight connector, so that if i ever have to drop the tank I have a connector right there.
