I'm not a fan of switches that don't do anything, personal taste of course, but in this instance, where you're trying to fit FL door cards into a PFL, the easiest option is to leave the driver's door switches as non-functioning dummies, so agree with Doctor Gollum above. I'm assuming/hoping that the electric mirror loom is the same for FL and PFL, and will just plug in? As on PFL and FL both are door-mounted, hope so, or with relatively little grafting.
Now, If I wanted to fit FL door cards to my PFL I'd either...
- install the FL centre console, too, and keep the door mounted switches, thus removing the switches from the centre console. I'd bet that where the front of the Centre Console meets the dash this'd fit fine, however, only way to know is to do it, of course. You'd have to get the electric window loom from the FL, and fit that somehow, tracing the original PFL wired from the centre console to the door(s). It's a fair amount of work...
option 2 -
-keep my existing loom as it, but make the door-mounted switch panels blanked off completely (excluding the electric window switch, which has to stay) with maybe a piece of sheet plastic with a piece of suitable, matching wood trim, leather maybe? something. It's a fair amount of work...
Make a blanking plate for your PFL centre console, by P38 filler/paint, whatever means at your disposal. As you can see here
To the best of my knowledge UK Omegas were always fitted with at least electric front windows, never wind up fronts, so a complete blank panel does not exist - unless it's to be found elsewhere in Opel's parts catalogue on the Polish spec early reg models, or something I'm not aware.
Tricky....
