Hello V8 community,

I'm new here in the forum, although I've been reading here for six months.

By the way, this is a great forum, I'm still on the road in other forums with respect to 200s and Uri, and I like that very much about the structure here, is also very clear.

First of all, I'm a technician in the electronics industry and, by the way, I'm just a screw on Audis, so right Audis: Urquattro, S2,200er and V8.

My field of expertise is the 10V Turbo and its tuning, since I have already realized a lot and also build various things as individual production.

As an everyday car I drive a 91 PT with 290 000 km on it.
Now that the oil eats like stupid (up to 5 liters on 1000km) I have to do something before it goes over the Jordan

I have now got a 92 ABH dispenser for quite cheap.Car is almost completely empty, but everything in engine technology and harnesses and STG are available, also the axles and exhaust system, oil cooler, pressure storage etc. Practically everything you need for conversion.

The hardware is not a problem, since I take everything necessary from the donor and overtake the heads and new head seals, timing belts etc., since the 4 years stand.

I know a lot about electronics, but now I have a question:

My PT is a 91 with an old climate and automatic.
dispenser ABH is a 92er with new climate and also automatic

Can I plug the 92 ABH wire harness at the bottom left of the dashboard at the Kostalstecker and plug it into my 91 PT and do it?
Or do I have to take over the wire harness that is in the car, so the further part from the Kostalstecker also from the 92er ABH?

If the occupancy is different, the schematic would be enough for me to surround it. Does one of them have them?
So practical circuit diagram of 91 PT and 92 ABH concerning the engine.
Without a schematic, it's all difficult.

Thanks for the answers.

Welcome
Manfred
