80-86 aero mirror upgrade wiring solution w/ one relay
https://rennlist.com/forums/928-foru...-solution.html
If you don't want to spend the extra $200 for the newer directions switch and select toggle switch in the well thought out solution above, here is an alternate solution using a single DPDT from RadioShack.
Relay
Socket
First picture is the original wiring decode by probing (fox/hound).
Second picture is the new wiring diagram, and the use of a DPDT relay allows one to use a DPDT relay in the drivers side door.
Third picture is the 85 944 transmission with extended break out cable with terminal block, as both sides needed extensions so the the Gray/Green is now Green, and Brown is now Red.
Fourth picture shows the ease of access via the coin holder or removal of the map pocket/arm/handle.

I have no idea what your "wiring" diagram means.... DPDT relays do not have standard pinouts - you need to reference it explicitly, plus I don't understand your symbols. You need to explicitly show the direction switch (by direction) and motors (by side & function).
It is certainly possible to do 2 relays (1 per side) with all local wiring (e.g like the plug-in adapters) or do 1 relay on the drivers side and I believe a single extra wire over to the passenger side. Or use new style switchgear and 2 extra wires.

I will replace the original diagram with a better one, that was my working model to do the changes. It does work logically with the lights and diodes.
All points noted, and thanks for the feedback.

What kind of debounce event are you expecting?

I'd not bother in this case - the diode across the coil is to protect a transistor drive stage - especially an FET drive stage - since here all we have is motors and switches there is nothing to damage. It still can cause spike coupling back to the supply rails but this is of little concern in most automotive case since the battery is a low impedance for direct supplies and many of the consumers are also low impedance on the switch (15, X) supplies.
Andre - haven't worked though all this yet - but this looks much better - Nicely documented - i think you have all the right parts shown now.

I'm not exactly sure what your trying to do I'm asuming you want to adapt the mirrors to work with the porsche wiring. My friend and I have been rebuilding the flag type mirrors using mirror motors out of a buick roadmaster from the early 90s its basically a plug and play the motors work the same way just have to match to the rights wires the only problem we had was matching the motors to the flag shell we ended up just bonding them in using black windshield adhisive. Not sure if this might make things easier

I think those investing in Aero mirros that come with Porsche motors already installed probably want to use the mirrors as is without modifying the motors. Besides Aero mirror have much less available space inside than flags. It is a little work when converting from the earlier single motor+solenoid to the later dual motor types but there are at least 3 ways to do it - all involve adaptation on the car side - either a wiring/equipment change or relay additions (or combinations of these) but are not otherwise particularly difficult - just fiddly.

Andre - Can you determine which of the wires does what ?
The pairs per motor should be:
M1: White & Blue
M2: Red & Black
Does M1 control L<->R plane OR U <->D Plane? (you may have to install to housing to determine
can you also determine the polarity of the movement?
e.g. if M1 is L/R does White (+) Blue (Gnd) Cause Left or Right movement etc for each pair
It is quite unclear from the diagrams which is which in both senses...
