Bill is saying to find a wbody 98 harness... Im saying you can just tear the connectors apart and pin them according to whatever PCM you end up with. You can run through each pin quickly enough, and you can rip out all the transmission, abs, ac, evap crap you wont use in the process.
The Jimmy will have "open slots" for whatever power was running to the old motor.. It probably has a dedicated ignition fuse, as well as a TBI fuse, and an ECU fuse among some injector or emissions fuses. my personal fiero basically has the ignition, half the injectors, and a few sensors running on 1 15 amp fuse, and the other half of the injectors along with a few more sensors running off the other fuse.. a total of 11 items running off of 2 fuses roughly if I remember right.
Throwing a junkyard relay in and wiring it up for the fans wouldnt be a tough deal at all.. Trying to fiddle around with that spiderweb box of fuses is far from worth the hassle for a small handful of relays.
