help e36 325 i swap m3 95 what engine harness do i use or can i use

[rayboost2000]

i need help i am installing a 95 m3 engine in my 4dr 325i . i received the motor without a engine harness. this is the problem i know that i can't use my stock engine harness off my stock motor because vanos did not come out until 93 n my 325i motor did not have vanos. since finding a real m3 motor harness is so difficult i was wondering could i use a 325i engine harness that has vanos on my m3 motor n will everythong plug right up because i have a m3 ecu but no engine harness .has anyone done this swap and use a vanos e36 325i 0r 328 harness obd1 on a m3 motor obd1 would reall appreciate the help n the right info

the 325 vanos and m3 harness are the same, same with the computer.

but arent the pins different from a 325i ecu to a m3 ecu do i have to use the same ecu the harness comes with because i was told they plug up but the pins mean diferent things so if i use a m3 harness i can't use a programed 325 ecu but if i use a vanos 325 i harness with the ecu chipped it willl work is that true
