Retro fitting Aircon

[Ben Purnell]

Anyone know anything about this, its not for the escos but for my MK6 RS2000, have been told that it may not be as simple as just fitting all the parts and the a/c wiring loom, apparently I may need the whole loom and ecu.

But I'm sure with all the right bits you can retro fit them on the escos, what the guy was saying its more the control of the idle that could be the problem if I don't have the ECU or whole loom

The bulkhead is different, as it has all the hose connections etc...

but nothing that couldn't be changed or drilled out though surely

the kit comes with the heater matrix and all other components, I don't mind if its a case of drilling a couple of holes for the extra connections, but if I go to all that work only to find out I need the whole loom and ecu I will be absolutely gutted, as I can't imagine it will be easy to find an a/c wiring loom

Ill be keeping an eye on this thread as I want to put the air con back in my car. Fortunately the wiring and evaporator unit are still there but I am now running a level 6 so will have the same idle controlling issues

[Ben Purnell]

but surely that ECU would have the capabilities as isn't that the one used in the later saffs

Can you really see Ford making two separate wiring looms, they usually have the wires there but nothing else for things like the heated screens, fog lights etc...

No, L8 is late Sapphire .

doh wrong again

[The Radman]

im not up to spec on the rs2000 system ben,but first off check to see if the loom is already there, look for the connections etc,if it isnt then i wouldnt bother with it

[Ben Purnell]

Nick which bits would you check extra connection for the fan, condensor, maybe heater control, I can't think what other connectors there would be

[The Radman]

there would be one for the pump,prob on the chassis rail loom,one for the receiver drier and one behind the bulkhead firewall area if its similar to the esc cos,i know theyre diff but there should be some plugs in those sort of areas ben if it has the loom already in

[Ben Purnell]

cheers Nick, this is what the kit consists of that a guy is selling
AC Pump
PAS pump
brackets & bolts
Matrix
Pipes
both radiators
Condenser
Wiring loom
dashboard control switch

which seems to suggest you can remove the wiring loom separateky, must admit I don't recall seeing any of those connectors in mine or the one I hve just stripped, damn sure there weren't many spare connectors on that one as I took the loom apart so I can rewire the MG

[The Radman]

does sound like it then doesnt it,any pics of it all ben? if he has the loom then it shouldnt be too dificult to sort it

[Ben Purnell]

that's exactly what I thought damn good price for a lot of work though but will be worth it

Long time since I've owned an RS2000, but I did look into fitting air con at the time. If memory serves the ECU is only different in that it lifts the idle speed slightly when the compressor is engaged to stop the engine from dying. You might be able to get away without that feature. The rest of the aircon wiring is relatively simple and could be spliced into the existing loom without too much difficulty.

For some reason I seem to recall that the exhaust manifold may also be different with air con in that one of the lambda probes fouls the compressor, so a revised manifold is fitted with it re-orientated.

It should be pretty straight forward and if you cant just add wire to ecu you could wire it to powersteering sensor in pipe which raise's idle when steering on lock
