Im fitting at autobiography front bumper and assumed wiring would be there for front parking sensors even though I didn't having parking sensors. Can anyone confirm if it should be there or not. For clarity I mean the wiring that http://www.ebay.co.uk/itm/Front-bumper-par...27d4237e76 this will plug into

I honestly don't think it is - apart from the sensors you also need parking sensor modules which I cant imagine are fitted ` just in case` if that makes sense. The fog light loom attachment is fitted and can be used - added.

Never done a sport, but disco 3 had all the hardware and wiring present. Fitted a bumper kit which included fog lights and PDS which werent present. The facility needs to be switched on by LR/faultmate user in canbus. I think rear sensors were standard on all cars, the front were an option  2x TDV6. SE and HSE. Both returned to sender with issues👀
TDV8 Sport HSE...... Gone. Loved it but it didn't love me!!
Now rolling in MY10 Fullfat TDV8 Vogue. Slammed it to go round corners🙈
Cruising daily #56 mph in a Volvo V8. 😱
Lots of other toys in the cupboard...😜

I think you right peachy. I can clearly see fog light loom but no sign of anything to plug parking senors into
