The central locking is just relays and they're in the door

and my UKDM doesn't have keyless entry but does still have the second box on the back of the ABS ECU's, as I can remember???

A quick Google search for that part number says that it's a 4WS computer mate.

So it must work with the other one then?

Yes, because the 4WS uses the ABS sensors if it's fitted.

Sorry guys, this is not a 4ws ECU.
That one is behind the back seat as said before.

ABS unit has got all Orange connectors, whilst this one has got green ones.

This is the TCS ECU.
Also attached to ABS and 4WS system.

Can't be TCS as Wurly said above his UKDM had this box, but TCS was only on JDM?!

The car from Paul72, was a JDM.
That car had a DSP front speaker, JDM climate control, JDM in dash tv (I believe) and the TCS switch next to his steering wheel.

This will show you the difference between ABS computer and TCS computer.

This will show you that a TCS switch has a green connector. The same as the slots in the computer from Paul72.

ABS is always orange.
4ws is way bigger by the way and has connector on 2 sides, not just one.
