Rear spoiler mod advice

Recommended Posts

Hi guys, After 30 years of waiting I decided to purchased my first Porsche.
I am now the proud owner of a 2002 C2 996 in basalt black with full black leather and a host of other options. Purchased from original private owner with 37K on clock ,a FSH and in immaculate condition.

One issue I am struggling to find information on is.............

I carried out the Rear Spoiler Switch modification as per following online instructions,
I am unsure about the wiring for the switch's illumination? The spoiler activates up and down as it should using the rocker switch so I'm happy with the middle 3 connections to the switch but hesitant to connect the other 2 to the switch as there appears to be 24 volts supply from the PSM switch supply connector when tested using a multi-meter? This is my 2nd attempt at this modification as I connected my original switch as per above instructions but had no illumination when headlights switched on. I returned this switch under warranty, not knowing if I had caused the damage myself by blowing the LED). Can anyone offer any further information on this?
Thanks in advance for all comments. Joe.

Wow... that DIY (on 6speed) looks just like the one Scouser wrote here a year earlier.... even the photos are copied. Scouser is from the UK and the car is his (note the RHD).

The Red/Blue wire on the PSM switch should be fused power (+12 VDC) -- A4 on the PSM switch.

The Grey/Blue?Brown wire on the PSM switch should be fused power is ground when the lights are on -- A3 on the PSM switch.

Thanks for your quick response Loren,

I'm mechanical to trade but far from electrically competent and could do with some advice on how to confirm the supply from the (PSM) switch!

Cheers Joe.

Firstly thanks to Loren for his great advice..

After much head scratching I have discovered that the switch I have wired in is different from the one shown in the modification pictorial.

The spade connections at the rear of my switch are 180' around from what is shown in the modification meaning the outermost 2 connections when reversed light up as they should! This modification has taken some time to resolve however it was well worth the effort.

Thanks again for all comments, much appreciated,

Cheers Joe.
