Lame question but I've bought a couple of DVD Headrests and plumbed them in to the front seats. I'm now looking for an easy switched 12v supply to plug them into. The seats have the lumbar bit and are heated so there are plugs on the floor under the seat. I was hoping I could t-in to one of those. Help, thanks.

 

You could do that. Just remember a few things.
1. "t" taps suck. strip and solder connections at all times, this is an Audi and not a Honda.
2. The 12v. connection for heat, power, lumbar are all fused connection. By adding stuff to the line you may exceed the fuse rating.
3. Audi's are noisy (electronically speaking) and you need to have a good clean source and ground.

 

Good lad. Thanks for the help.
