Hintergrundinformation:
Shiftfan hat einen E34 ohne Klima und hat sich jetzt eine IHKA eingebaut, die er nun versucht anzuschliessen.

Hello everybody.
I want to install an AC system on my bmw e34 because it wasn't equipped from the factory, can anyone help me with the electrical schematic ?
I know that i have to link the DME, the pressure switch from the AC, the auxiliary fan, the IHKA and the temperature switch in the radiator in this equation, how do I do it ?
So far i know :
- that there is a temperature switch which gives signals to K21 and K22…
- that i have 2 relays k21(normal speed) and k22(high speed)
for the auxiliary fan, and when the compressor turns on the DME has to bump the rpms to compensate.
- there should be a compressor relay (k19) who links :
1.signal from the IHKA
2.a signal to relay k21
3.a signal to DME to announce it to compensate...
4.pressure switch
5.compressor(Y2)
Can anyone help me with a rough schematic? or explain how the entire system works
PS:I have a ETM manual , but it dosen’t cover the IHKA version, mostly the IHKR II.
-------------------
Who has IHKa on their E34 and can tell me where do these connectors go ?
So far, i know that they are from the heater electrical system and i think the connect with something under the steering column, and near X35 (heater connection to the car electrical system.)

Hab ihm schon in einem US Forum den Link zu Gunnar525 gegeben im Juni:
There is a German language DIY site
Meine BMW Geschichte
Click on the left side on Schraubereien, then go to
Belüftung / Heizung / Klima , and there to
Umruestung bei vorhandener Klimaanlage auf Klimaautomatik, that are 72 pages instructions how to convert from simple climate control to IHKA, you will see all parts to be replaced and comparison pics of all components
IHKR/3F to IHKA.
Check the E32 ETM for function diagrams of IHKA system
BMW Wiring Diagrams
Training material for technicians in German language

Das war im Juni, nun hat er eingebaut, muss aber noch die Stecker anschliessen beziehungsweise wissen fuer was die sind, vielleicht kann hier ja jemand helfen.
