Rb25de neo wiring loom question

[Er34_luk3]

Hi guys I’m buying a motor for my r34 it’s a auto and the motor I’m buying is out of a manual 34 can I use the loom on the new motor with a auto ecu? My auto loom is rooted ? Rb25de neo

I highly doubt it, I'm 90% confident the auto loom is part of the main engine wiring loom and the manual one won't have all the wires and plugs you'll need.

We reused my original RB25DET auto loom with my manual conversion and it worked ok (incl. speedo, reverse etc.) after some minor adjustments. From memory some original plugs are currently disconnected.

Why not do a whole manual conversion whilst you're at it?

Yeah was thinking that it’s so hard to find a full auto loom these days need a auto ecu as well. It’s my wife’s 34 she can’t drive manual ☹️ And the auto is pretty mint still
