      LS3 Fuse Box Terminations

      I'm trying to take some of the wiring for the LS3/T56 Install. The instructions that came with the GMPP harness/fuse box are meager at best, so I'm looking for a little help with integrating this with my Painless harness.

      As of now (It is stuffed in a corner and I'm really not sure at this point if I'm going to keep it there since it may get wet

      Grey: fuel pump
      Blue: fan

      However, I saw from another thread where someone was putting in an LS3 that those two main studs have wires connected to them as well (roughly 12 gauge). I assume at least one is a power wire. Can anyone offer some direction in this department? How many connections should I plan to make to get it to mate to my Painless harness? I have almost no idea how to wire this up due to the lack of instructions that came with it. I have already mostly installed the Painless harness throughout the rest of the car, so I assume minimal connections need to be made.



      I'd really like my fans to be powered per the attached:

      (two electric fans) but the LS3 fuse box only has one relay and one wire. I have other external relays ready to go under my dash, but I have read that it is better to have the ECU control the fans.

      Here is some info on my ECU if that helps...
      GM Racing
      GM# 19258268
      Gr. 3.670
      GM Performance Parts LS376

      Also, the diagram on my fuse box cover is faded after being left out in the sun for a day, so if anyone can provide a screenshot of theirs, that'd be great. Or...maybe I can just order another cap?
