5 pins on the Footwell Light switch explanation?

[LVDell]

So I've looked at every thread imaginable about adding the footwell lights to the car but I haven't seen anybody just add the FWL switch and connect it to a set of lights you can turn on and off at will. Most all the installs tied into the doors and dome lights. Or they are tied to the dome light with no switch. I just want to install two lights ( 1 driver and 1 passenger side) that are wired to the switch.

Here is a diagram of the switch. Since i don't know anything about electricity I'd appreciate any input from those of y'all that understand it. Trying to figure out what Porsche did to wiring up those lights.

The goal of this project is to wire those two lights to the switch and have the switch act like it was factory to begin with (lights up with the rest of the switches)

TIA!

The Footwell Lighting option is MXX2. The wiring schematic for this option is on the upper right corner of the Alarm page (usually page 8) for each model year. The key parts to the option are the a) two lights, the switch and c) two relays. The reason the switch connections don't make sense is because they are designed to toggle the relays and not toggle the lights directly.

I installed this option in my car a few years back. However, I wired it up with just one relay. The relay is a bit spendy which is why I just used one. I believe I collapsed all of the relay connections into relay 2. Everything works fine. It powers up with everything else, lights up with the dash lights, signals that the lights are on (kind of redundant) and the timer works too (the lights shut off after some period of time). The lights themselves come in very handy from time to time.

I have attached the MXX2 schematic for you. I've zero'd in on the MXX2 section so you can read it better. Thus, you can't see the following: The Bn/Ye wire from A5 on relay one and the Rd/Bk wire on relay 2 connect into the two groups of similarly colored wires under the dash. If memory serves, you'll find a place to tie into these down by the relay panel.

I can dredge up the various part numbers if you'd like.

The switch requires a relay because it closes a circuit only when it is pressed. Once you let go of the switch, power flow through the switch ceases (except for the backlighting circuit of that particular switch). A lot of automotive switches work that way. When you press the switch, power energizes the relay to open or close. The relay is essentially the device that controls the flow of electricity in the circuit; the switch just tells the relay to open or close. You can do what you want to do, but just not with that switch alone.
