Hi Seba3003, welcome to the forum !!, in the Caja Changes, you will have a back switch, this is usually found over time, (check it), as for the portalamparas, look for some in a scratch and pick them up the plugs cut by the cable, so that you can connect it in the wiring of your car, observe if your car has the car) Here we are. I am already for him !!
** (CAUTION When disassembling the switch from the gearbox, if it is in the lower part, you may get oil) **
