Seat Toledo

I have a Seat Toledo Ultima generation and tube a blow and since then the lights are always lit, I have been in the official workshop and they tell me the problem is the centrlite, my question is whether I can cancel it and put the traditional system with relays and switch. Or while there is any other solution to avoid changing the switchboard, thank you very much.

If it can be eliminated, but it is best to make a parallel installation, just eliminate feeding from computer to the lights, it is better that an electric is aga if you are wrong you can do much badly, luck.
