I don't know where you're located, but just wanted to be sure you have already checked the laws on engine swaps in your state. Here in WA, you couldn't do the swap you're talking about - at least not if you want to register the truck.

Around here when you do an engine swap you have to transplant an engine that is as new or newer than the vehicle it is going into in order to be able to register it. A 92 motor into a 99 couldn't be registered. I'm sure you've already checked on all that stuff for where you live. Just sayin'...

As for the wiring question, that will be a bit tough, but do-able. I'm doing the same thing on my Diesel Cherokee build. I started with the engine wiring diagrams for the Jeep and began by eliminating all the wiring for the ignition, computer, and emissions, just keeping the switched wire to the coil (for the fuel cutoff) and the starting and charging circuits.

Next I'm bw taking the wiring diagram for the Olds that the diesel came out of, and eliminating any emissions junk, and keeping only the wiring for the glowplugs, starting, charging, and fuel cutoff circuits.

From there it is just a matter of splicing the two together. For your project, the process should be similar...

 

thanks creeper but im in florida and pretty much any thing goes here since there are no emissions to pass but that sucks that thats the way it is in some states because buildin a custom ride is kinda bringin stuff together and makin it work no matter how pro you are u always find some thing that will work and thats what its about
