If I read this correctly and your remote is the same as the OP's then you need to take what is my RED (4) cable and splice it into 2 and put both reds South of the switch and LED on the Remote, and each of the Blacks (1 and 2) go to the North of the LED and North of the Switch respectively.

I gave mine back a long time ago! :floor:
My switch is on order from Hatfield OPC whom reports 'there have been a backload of these orders in the last few days - what's going on?' :grin:
God knows how I am going get mine to work if Markiii can't!

ok I prepare to be told I'm talking utter tosh, in fact that may even help, but..
the homelink switch when pressed connects the common (Pin 4) to both the switch (Pin2) and the LED (Pin1)
so effectively at this point all 3 are at the same polarity
so if I connect the switch pin to the high side of the PCB switch and the common to the low side of the switch it does what you would expect, remote operates
however for the LED on the switch to light (its a diode so can only be connected one way) it needs to see positive on the Switch (Pin1) and
-ve/Gnd on the common (Pin4) this is proven if I connect it in isolation
however it can't see -ve/GND on the common Pin at the point at which you press the switch because the common (Pin4) is now connected to the +ve (Pin2)
in a nutshell wtf?
hence my question about the unused Pin3 which if it was a GND for the LED would make perfect sense
I can rig it so the LED is on when you don't press the switch and off when you do (though obviously that's crap as it will kill the battery)

Which pins do what on the Porsche switch ?
With my remote the 12v +ve is fed to one side of the switch and to one side of the LED. I have therefore taken three leads from the remote, one the common +ve, two the other side of the switch and three the other side of the LED. I have yet ot get the Porsche switch and would like to know how it is wired. Thanks.

Pin 1
Markii - do you not just need to reverse the polarity to get the diode to light up?
My GCSE taught me better than your degree - keep it simple.
Pin 1 and Pin 2 when the switch depressed allows the current to flow through to pin 4 hence closing the circuit. All you need is +12V running in that direction to both close the circuit to the OE switch and supply +12V through the diode.
so having taken the switch apart for a more in depth look
heres what we have, that dead pin 3 is connected to the other LED that's sits in the switch itself,
oddly whilst its connected between pin 3 and common, applying 12v across the led does absolutely nothing
