I just want to thank lollapalooza for his time and great posts, I have a '59 plate Zetec S, panther black, had it from new and is mainly used as a second car. In my opinion, any position other than the factory locations on the Zetec S, spoil the look of the bumper, so have been searching for a solution for ages, the dealer fit X-vision ones go across the bumper and don't look factory at all, so did not personally want to go down this route, to retrofit the original system would be close to impossible as CAN pathways are utilized and lesser spec cars have different looms and modules, so, just not worth it.. The great thing about the Bosch Park Pilot URF 7, other than the quality of the components, looms e.t.c. is the fact they are able to function low down in the factory positions, so it was a great find by lollapalooza, I now have a Zetec S that looks almost identical to one ordered with factory sensors. The factory markings are clearly visible on the Zetec S diffuser and bumper, so there is no room for positional error. I was present when my body shop did the work in Westcliff-on-Sea. The Bosch URF 7 can be colour coded to match the colour of the diffuser and rear bumper and as I said, work really well. For anyone like me who wants the factory look, go for the URF 7 from Bosch, great bit of kit! Thanks lollapalooza.. LEGEND!!!
