The wiring for the 1JZ isn't that hard really as long as you take the time like I did and put in new harness plugs instead of soldering the connections for the four plugs you have to replace. I just bought some harness plugs that had enough pin holes to work and then bought the pins and did mine that way. As for the main engine harness you don't have to extend it you can always use the tuck like most people do it helps keep the integrity of the original harness.
