    RB25 Series 2 ECU wiring

    While I was doing the wiring for my RB-S13 harness I found the perfect Series 2 ECU pinout, every wire was exactly the same as mine. It took me a good hour of sifting through S1 pinouts labeled as S2 and threads upon threads of people saying that they're the same. Unfortunately I am an idiot and didn't bookmark it when I had it open and lost track of it somehow and haven't been able to find it since.

    I know most people say that the S1 and S2 ECUs have the same pinouts but I know mine did not match up with the typical S1 pinout like this: http://wiki.r31skylineclub.com/image...CU_Pinouts.jpg

    Anyone come across this before and happen to save the link for that magical pinout? I would love you forever.

    Buy a translated to english factory engine manual for R33 RB25DET from link below, that should have pinout, wiring diagrams, etc in the back for both Series 1, 2 R33 RB25DET engines -

    I have the complete FSM on my computer, it doesn't have it.

    I figured out what I needed anyway without the pinout so I don't really need it anymore.

    Please post up if anyone has it though.

    does anyone know if the pinout would be different from the r33 to the C35 laurel RB25?

    How did you tell yours was from a Laurel?

    That may be why my pinout isn't like other RB25s.

    There are a bunch of wires going places they shouldnt on my harness, and a bunch of colors of wires dont match up.

    upon closer inspection the ECU was lightly scratched "koki laurel" and the ecu part number is different there is T in it rather than the U for a skyline ECU.

    All this info is second hand since the guy at the shop working on my engine knows the specifics.

    Here is a pinout for the series 2 engine I found trying to find info, is this the one you were looking for? http://www.s-chassis.com/resources/w...C_RB25%2C_RB26


    Is your car running yet? This was supposed to be a qiukc swap in my r32 but it seems like its getting increasingly difficult.
