I've decided to start researching this further...looking at other forums for different cars they work as a cosmetic by just changing the panel...but since this is a peugeot forum, we cant do things by half and have to show the bmw and merc owners how it is done properly....
now what i have found is on the manual controls there are 3 plugs that go in the rear - same as the auto, but different amount of pins and style of connections on 2 of the plugs. also on the manual there are 2 pull wires, 1 does temp the other, which way the air goes....
now if i am thinking right or this night shift is messing with my head, the air all comes from one hole, in the center near the bottom of the car, some sort of regulator, obviously this needs to change to the auto and the harness to go with it.
the other is the temp and again this goes to one place (not to sure yet) - need more research on this end.
another thing to install is the internal temperature probe (to display on the control screen) this fits into the peice on the center console that has a few horizontal lines. this will also need a harness...
sounds kinda simple, which in theory it should as dealers offer this as an addon, or am i wrong here. i think someone with full servicebox docs could clear this up.
any other ideas. Here are a few pics to help
back of auto panel (ignore the circles made by the cheese eating surrounder monkies)
i cant find a pic of the rear of the manual to show the differences and similarities
