Preliminaries:
The following is for a 1994 and 1995 built 993s with no immobilizer installed and no factory remote. I do not know anything about immobilizer and its functionality when it comes to controlling the door locking.

The procedure is very simple, it could be done in 30-40 minutes total.

You will need:

Some sort of remote door opener. I used a $30 JC Whitney unit that I already had, but there are dozens of them on the market.
6mm hex (allen) wrench
10mm socket
Small flat blade screwdriver
Wire cutting tool
Wire crimping tool or some other method of attaching wires
Voltmeter (optional)

Procedure:

1. Take out the passenger seat. In order to do that you'll need to undo the 6 hex head bolts (6mm) that hold the rails to the floor. Raise both the front and the rear of the seat to the highest position to give yourself more room. Disconnet (pull off by hand) the connector under the front portion of the seat before removing the seat from the car.

2. Once the seat is out you will see this:



Red arrow indicates the Porsche "Control unit/Central Locking".

3. Unscrew the 10 mm nut on the side and carefully pull out the control unit. The thick black wire is held by a metal connector that is fairly easy to break, but since the wires are not moving, that's not a big deal.

4. Detach the yellow connector as seen below. In order to do that, pry up the black plastic slider in the middle with a small flat blade screwdriver. Once it's up, you can just pull on it with your fingers or a larger screwdriver. Below is what you'll see: arrow 1 is the connector, arrow 2 is the control unit. Black connector is also disconnected, but you can leave it connected.



5. There are two wires going to yellow connector that you will need. One is Brown/Blue and the other is Brown/Green. Brown/Blue is "Lock", Brown/Green is "Unlock".

6. Connect the "Lock" and "Unlock" wires from your remote control unit to the two above wires. You can do it in several ways. I did it a about 4" above the yellow connector. Unwind or cut the gooey black insulation tape first. Don't cut the wires too close to the connector. Once the connections are made, re-tape with electric tape.

7. Remote units differ, but most universal ones have a polarity wire (often white). It can either be connected to Ground or +12V. In case of 993 you connect it to Ground. So, attach the polarity wire and ground wire together to the convenient Ground connection that can be seen on the first picture (brown wire with a lug is connected there).

8. Connect you fused +12V (usually red) wire to a convenient +12V non-switched power source. You want to make sure that +12V is present with ignition off, as that's how you are going to use the remote. Most power leads on universal remote controllers are already fused, but make sure it is.

9. Connect the yellow connector back into the controller, screw the controller back in. Get outside, close the door, push the buttons, make sure the car locks and unlocks, drink a beer. Or don't.

10. You can attach the remote unit to the top of the factory door controller if it's slim enough not to interfere with the seat. Put the seat back in, connect the power connector under the seat, bolt the seat down, drink another beer. Or don't.

Optionally you can connect the lead to have the car blink the parking lights when locking or unlocking the doors, but I never did that in any of my cars, so that's where my instructions stop.

The entire procedure can be done in 30-40 minutes.

The original discussion revolved around the ability to arm the alarm while remotely locking the car. Mine seems to be fine, the red LEDs in the doors are blinking as they do when door is locked with the key.

If you have any questions, don't hesitate to contact me. If this is to be put into a DIY collection on Robin's site, I'd like somebody else to try it to make sure all the steps are described well enough.

I have a 1996 993 with no Immobilizer or remote and tried to follow your procedure until I got stripping back the black gooey tape and didn’t have to colours that you described. Also you mention a door opener, are you describing another door solenoid to be fitted in the drivers door?
