rgajr over at clublexus did this years ago (on gs300) and it's impressive and worth a read. lots of good info there. all credit to rgajr.
started this on the sc400 but since it's incredibly tight quarters in the sc400 and there are always bigger fish to fry, have postponed (procrastinated?). also the pioneer will eventually come out of the sc400 & go into the lx anyway (has rear channel audio/video so would make more sense in the lx).
steering wheel w remote controller is in sc400 and sourced a wheel for the lx450
to go this route, depending on what airbag you have, you may or may not need the airbag sub-harness adapter. i needed the same adapter for both the sc400 and lx450. you will also want to check donor vin for airbag safety recall.
sourced bunch of resistors but plan to use axxess adapter kit (picked up both universal & toyota/lexus specific) to try to keep from hacking oem controller.
ideally the headunit should have remote control input.
not sure which wheel (black leather or wood) would look best in lx and originally wanted to use lexus/toyota phone controller but it's smaller size than later controller. so it's newer wheel over original (prefer original lx wheel but needs a wrap so thought well why not try different wheel)
cheers
