2.1 TD variable power steering

[rwb]

Again for midsmike.

There are two variations of the variable power steering, they swap over at build code 07706.

The part numbers for the racks are identical, but the control modules are different:
The earlier one is made of two parts, and is described as:
4016 08
NFP
STEERING SERVO-REGULATOR

and

4018 P8
NFP
ELECTRIC CLIP-HOLDER

These are shown as being located at the passenger side. However, the diagrams are unlikely to have been converted for RHD, so it could well mean the driver's side.

The later one is a single part, described as:
4016 08
NFP
- RIGHT HAND DRIVE UNTIL RPO 07728

So, it's identical other than the absence of the 'clip holder'. Again, shown at the passenger side.

I couldn't find any more detail about the location of these -- not even which side let alone what part it plugs into.
