I have AE-90 since 2000. Now i am thinking about swap with 4AFE. The only matter of concern for me is wiring. I kept this car lots of care never let anyone to play with wiring it is still in its genuine tapes. my question is how much alteration required in wiring??? whether it will complete new wiring or have to cut the original wiring for joints??? please guide
one thing more i wanted to know there is sum of sort of diagnosis panel in my car what is that for and it also has ECU sort of thing mounted near A/C blower under dashboard, as far as i know 2E have nothing like ECU. what is that for.
I am uploading pictures of diagnosis panel for better understanding.
Thanks
