Hello i have an volvo v40 of the year 1997 and i buy an headlight of the volvo v40 t4 with the kit xenon
i don´t know how modifie the electric scheme to work with the new headlights
anyone can helpme how change the headlights?

 

i think you need to do the cabling modification first, because the t4 i suppose to have double headlamp ( h7 or h1 bulbs) while the normal have the h4 bulbs (low & high beam in one bulb)
