urmmm not too sure dude, thats 1 thing im not good at is wiring but for taking the lights out you can simply unplug the wiring from the back of the headlights
i had airfilter, obx racing 4-2-1 exhaust mani, decat, rolla mani and made about 13 bhp on top of standard all in, mani to exhaust cost me about 550-600 squid not cheap just for the exhaust
yes, and there is also like a ball and socket joint on each headlight too dont forget to disconnect the wiring before trying to yank the lights out too
told you to keep that quiet dude :/ spent a good few hours diggin the gfs car out, until my brother came up with a brilliant plan, strips of carpet FTW
