I have just purchased a new rear bumper, for '02 connoisseur that has no parking sensors, which is fitted with Rover sensors and from a scrappy, the controller, sensors, wiring loon and sounder, does anyone have a wiring diagram showing how the sounder is connected to the rest of the items?

You will need to look in the boot on the right hand side behind the boot liner, there should be a wiring plug for the parking aid box, the picture below are for an MGZT but the wiring plug should be the same.


R75 & MG ZT rear bumper removal and sensors.
Earlier this year I decided to change my rear bumper for one which had the sensors fitted below is a pictorial of removal and re-fitting.

There are four fixing points under the bumper two centre and one each end at the rear wheels

Rear wheels end should be a self tapper or 10mm bolt Fig 2

Centre two should be plastic scrivets either side of the towing loop, Fig 3/4

The bumper I removed did not have sensors this being the reason for removing, to be changed for one that as sensors fitted. Fig 17

Another top class how to Steve.

Yep, another excellent tutorial, Steve.

Excellent "How-to" Steve, thankfully, Phil-T4 (Testbook version 4.Computer Diagnostic System) fitted sensors to Ed's original bumpers, when he was still doing stuff from home!
