My E34 has been recently retro fitted with electric seats which I have working after fitting a new loom. The only part I have struggled with was the heated bum warmers. The wiring is there at the plug on the car side but strangely nothing is there at the fusebox, just an empty slot with no connectors.
So my question is, would it be safe if I jump a power wire straight to the car battery with an inline fuse installed or should there be a power step down somehow. I'm not too clued up about electics but will have a go and wouldn't do anything without good advice and making sure I'm happy something is safe.
