nice XJ haul!
the fuel pump ballast resistor can be simply bypassed if you ever have doubts about it. it's not necessary for functionality, only to make the pump less noisy.
some of the parts you'll want to buy new (you'll find them individually, not as a kit), but most you'll be grabbing from the junkyard (the hvac box and hoses for example).
do you have a multimeter? the various sensors can be tested. also you should accomplish all of Cruiser54's MJ tips. most are electrical related. all those things can be found in the link in my signature.
I'll happily take any MJ emblem that's missing. I do have the individual J e e P header letters but haven't figured out how to mount them without popping off the studs.
finally got some on the north wall. and yes, one of those is NOS. still need a metric ton and a select trac. the cherokee emblem is a filler until I get those.
huge thanks to the guys that sent me the missing items.
