Hi all
I have a lexus SC300 1996 model-manual with a 2J injector engine,
But I have bought a 2J Turbo engine and I would like to make sure that every thing goes well with the new 2J tubo engine.

Thus, I have some questions (Hope that do not bother you friends):

(See the picture provided please)

1- I would like to know what is the best and the correct way to arrange the wiring system so that everything in the car works and functions well without any future mistakes ?? (Such as the interior lights)

2- I would like to know if any of you has a complete project regarding changing the SC300 2J injector engine to a 2J Turbo engine.


I really would like to keep away from engine and wiring system problems.

I will be very thankful for your help friends.
