I found an '83 240D with manual heat and AC controls in one of the salvage yards and want to swap it all out with the auto controls in my '83 300D.
The only real concern I have is trying to find out what supply and return hoses I'll need going between the engine and heater, I'm fairly certain those on the 240 won't cut it, and a quick search on Autohaus AZ's site didn't give me much confidence.

Anyone have a diagram or photos of these hoses on their vehicle?

Thanks for that. I picked up 47, 53, and 32 today. May need to order 14.

Connectors the same?

I'd like to do the same conversion. Does the manual control panel plug in with the same connector plugs as the auto control module or is some wiring required?
