89MJ4spdman2wd

so would I be able to go and get any 93 mpfi under dash harness and do what your diagrams say basically plug the 93 main harness into the wall under the hood and re wire under the dash and then just get rid of old 89 tbi harness

I wish it was all there. Sounds easier to rig up So the XJ harness is the one for under the dash as in the black and grey one or the big one under the hood How can I post pictures

The harness was attached to the engine I was told it came out of a 93 Cherokee Rwd with only 38000 km on it the 5 speed transmission was attached as well

I have the computer the fuse box and battery clamps under the hood i have nothing for in the cab the write up shows for under the dash correct nothing about under the hood rear harness is where also what does HO era mean also the Renix era confuses me TBI Renix MPFI non-Renix ?? Sorry for all the questions posting picture ...How

I did look at the charts But what if one does not have the donor plugs for under the dash. Should i try to get one? Also how or what do i need under the hood for the plug that goes into the fuse box i sort of understand the pulling of pins and moving them any help would be nice i look under the hood and am just over whelmed

Gavin here again Also any other information on the Vacuum lines Mostly any information on rewiring the new harness into the old or is it vice-versa I do believe it won't be hard but a time and patience job And Help From Good People Thanks again all out there helping this Newbie
