Check out this post from a few years ago. Todd found it is an ECU. Not sure what its doing in a TD42 car though? Is it possible that your car has had an engine conversion done at some stage?

@Winnie maybe it controls the injectors?
Bit of a mystery eh...
IIRC to date those "ECU's" have only been seen on 24 Volt Safari and Terrano (overseas models).
I don't think they'd put the TCU in unless it was going to be an auto but as far as I'm aware the only factory auto 4.2 td were 94 that's with Nissan Aust on the compliance plate .
Have seen one that had been converted to a manual so it's not impossible but the compliance plate will tell you country it was sent to and transmission it had .
