On the aircon there's a separate circuit board for fuses etc left of slam panel so must have been a challenge to get that all wired in - unless you've installed it with a separate circuit? Difficult or what?
It's a little verbose, but the detail of retro fitting climate control to a phase 1 is in this thread :
There's quite a lot of detail there and once it's all up and running I'll post a full parts list.
In summary, the basic task list is :
Add external temperature sensor to door mirror and add wiring to door loom.
Remove dashboard and swap p1 heater unit for p2 climate unit. This also requires modifications to the steel behind dash crossmember ( I'd recommend getting a p2 xmember from a donor car ), steering column support arm, changing all the under dash ducting and modifying the new ducting for the P1 rectangular central vents*. Electrical work means wiring to the external temp sensor in the door mirror, a feed from the speedo, a new 30A supply for the fan ( not difficult ), wiring from the car's ecu to the engine bay and from the climate ecu to the engine bay.
In the engine bay fitting all the pipework, compressor bracket, compressor, receiver/drier, new aux belt and pulley. Compressor relay and connection from the pressure vavle on the receiver drier to the new wiring from inside the car.
If the car has p1 aircon, the electrical work is simplified as a lot of the wiring is already in place, but pretty much everything related to p1 aircon has to be thrown away ( compressor & bracket, evaporator, receiver/drier, condenser. The only common parts are the auxiliary belt idler pulley, the compressor relay and the pressure sensor on the receiver/drier!
* Fitting climate control actually makes the job of fitting a p2 centre console a lot easier! I haven't decided whether I want the p2 console or not. I'm probably staying with the p1 interior at this time.
