Any help on this topic would be appreciated.

Well boys and girls thought I would share info with you.

You can't install a volume switch in an LX missing a volume switch. Unless you swap the entire under dash wiring harness.

Sorry dudes and dude-ets this is too price for me.

My remote volume switch is also called "co-pilot", "navigator", or "honey". It'd be much more expensive to replace her ;)
