Hi I have bought a kit of parts from a breaker to upgrade my car to Air Con. Can anyone tell me if the main front to rear compressor pipes run through the car or under the car? Dave K

under the car parallel to the radiator pipes. I think you need to bolt off the reinforcement panel for easier access. Must get put back of course. But that's the easiest part

Thanks Dieter.

I think sorting out the wiring is going to be the most difficult part!

yep
I recall there where 2 of specific looms for the AC control. Switch etc and front dryer bottle.
The main harness includes the wire for the compressor already at all MGF versions. ( connector behind the ECU leading to the other connector behind the fuse panel. )
