4.0 swap wiring
1st post on this forum. and this is prolly covered many places elsewhere, but ive done my 4.0 swap, and its wire time. ive run into an odd problem. theres dozens of good sites about this swap, but everyone seems to favor an xj swap into a yj. ive got an 87 yj. and i swapped in a 4.0 from a 91 YJ. so i did a yj/yj swap. the best i can figure is the chassis harness is the same from 97-91. and since this is a 91 engine i SHOULD in theroy be ok. i just need to plug the fuel pump power wire into the bulkhead connector. and splice in my gauges. im hoping soneone here has done this, and can give me a lil insight. thanks .
