Parking sensors fitted., No problems.
I didnt have to remove the trims, instead I lined the sensors up on the bottom edges of the inserts in the factory locations, so each end of number plate, and centre of the 2 reflectors.
No issues behind the holes and went though the trim and bumper in one go on the drill.
Got some paint for the sensors off
seller and its a perfect match.
All of the cables underneath then lead to the centre and finally through a grommit under the floor under the carpet where the sixth or seventh seat is located (grand voyager).
Cables then routed under the carpet to back trim and the connection unit is tidy under the trim between seats 6 and 7 where the tool kits is stored.
Wired up to the drivers side reversing light which is + white wire on the far edge of connection block and - black wire in the bundle of other wires.
All worked fine, no erronous readings from the system from the ground etc so at that height they are good.
