Mate of mine has a 1996 P Reg Caddy van which I know is based on the Polo of that era.

He wants to fit heated drivers seat and understands that the wiring for such is in the wiring loom.

Can heated front seats be fitted to the Caddy and any recommendations re independants who can do this work in the UK
