I'm changing my 348 taillights to 308/328 taillights simply because it looks A LOT better. The 308/328 yellow/white lens is pretty obvious what happens. However, since I don't own a 308/328, I'm not sure what happens in the red lens. Since they (Superformance) didn't send the bulbs with the lens I don't know if both bulbs are duel filament or not. And what's going on with the backwards bulb socket (with the white/blk wire) in the middle of the red 308/328 lens? Engine light? I am NO expert when it comes to wiring, so if someone here can help me match wires in my wiring diagram, I would really appreciate it.

Here's a pic from my 85 QV that may help. The yellow/red pairs are for 2 bulbs, the black is grounded to the housing. The middle hole in the housing isn't used. The 2 bulbs are double-filament (I'm using LEDs.) The yellow/red terminal assignment DOES matter; get them backwards and you'll have full-time everything, instead of only parking lights when applicable. I suggest using blade connectors on your pigtails, so it's easy to test and switch the terminals if you get it backwards. (Or if you're soldering, test it first before you commit.)

Cool For the red lenses, I'm using Sylvania 2357R LEDs - these are RED LEDs. (You want to match the lens color to the LED, for best results.) For the yellow lenses, Sylvania 7506 LEDs. (Yellow or Cool White, depending on bulb position.) These are easy to find at PepBoys, OReilley's, AutoZone type places. They don't have LEDs on the top of the stalks + the sides, only around the side. So a bit less "head on bright", but loads better than standard filament bulbs. Also, you need to replace the yellow bulbs all at once (front and back of car) - and possibly your "flash relay", otherwise you might get hyper-fast blinking turn signals.
Found some pics I had saved from an ebay listing. Image Unavailable, Please Login Note the red center is not used on this one - as mentioned in your other thread I assume they are for euro fog lights. Image Unavailable, Please Login
Meant to mention this - one thing on the bulbs: Check the receptacles, before you just go and purchase 10-12 bulbs. On mine, the amber/white posts are different than the reds - so, 2 different (not just color) bulb types are required.
Euro-fog lights are separate lights mounted below the rear bumper on both the 308 GTB/GTS and the 328 GTB/GTS series. The centre diameter of the red lenses are rear reflectors, nothing more. The reverse facing bulbs on the holders for the red lenses are for trunk lights on the 328: http://www.ferrarichat.com/forum/threads/my-328-has-trunk-lights-wow-hi-tech.447752/
