I have seen a few write ups on how to cut the physical headrest, but how about wiring. I was going to tap into the cig line, but not sure if that is a good idea for 2 monitors. If I did choose the location can I tap into the ground on that too? I have also heard you can go directly to the fuse panel, but to which one just any empty? And how would I do that?
Any help is appreciated.

 

I'm a little curious what's best too.

I just put in #1 of 2 headrest monitors. I planned to run them both off the accessory (cig.) I'll connect the ground someplace as close to the monitors as possible though. I also planned to connect the ground somewhere beneath the centre console. I'm going to put an inline fuse right at the accessory connection too.

I definitely want them on a circuit that cuts off with the key off though, like the accessory.
