Not sure if anyone has viewed this thread in awhile, but figured I'd add some info. The splices detailed in the instruction ARE the only way to go (at least with the 2003 rubi). While removing the locker pumps I started to trace wires to see if they could be removed and rerouted in the engine compartment. I found the factory intermittently wrapped the wiring bundles in electric tape prior to being placed inside the wiring loom (the loom that is routed over the transfer case and head towards the passenger side of the engine compartment. I also found that the ground wires for both pumps are connected to a larger gauge wire, all of which is headed into another wiring loom. This loom is routed towards the driver side of the gas tank and I believe is then routed over the gas tank towards the passenger side.
