with any motor swap you have to answer a few questions. what do you want to take and what do you want to keep. i don't know anything about samis. lighting up the steering column and ignition shouldn't be a problem. but what gauges are you going to use? if you're keeping the sami's gauges are they mech or run off the cpu? since you have the whole donor take everything before you part it out. in my 4.0 swap i took every wiring harness. i would take all wiring, steering column, and speedo cluster. that way if you find out that the sami componets wont work easily with the 4.3. just swap in the stuff from the 4.3. good luck
