OK, so I know this has been documented several times as you can see from some of the photos I lifted from other threads. Everybody seems to think it's difficult to upgrade with this "22pin" molex plug, etc. It's just like any other stereo install. For starters, don't be freaked about cutting the molex, its an 18 year old sub 10K vehicle. Follow the simple schematics (several shown) and do one wire at a time. Go buy a cheap soldering iron/ gun and some heat shrink and get at it. Double butt connectors will work if the soldering seems overwhelming.

The only "parts" needed are (2) line level to RCA adapters that you splice in and the trim plate off of Amazon for $27; just type in "LX470 stereo trim plate" or something similar. The factory radio brackets work fine, you'll just have to space 3 of the 4 corners out (not the top right one) when mounting the unit in the dash. I used some nuts as spacers and slid them in between the dash and brackets, pretty self explanatory when you're doing it. I taped the face plate to the backside of the dash just to hold it in place during installation as the stereo holds it in place once installed. This wiring setup allows you to use the factory amp as long as your aftermarket stereo has RCA outputs. Everything turned out aesthetically pleasing and it sounds great, (I bought the ground loop isolators mentioned in other threads but they were not needed for my install). There's nothing intimidating about this install, just get on it.

Yup, I can confirm it's not that complicated. I didn't have any issues with the factory mounting brackets, though. The only trouble I had is getting the RCA connections to fit, depthwise, with my particular head unit but, otherwise, it's all very straightforward.

i brought this up a couple days ago in my planning. Did you run the new HU ACC to the Amp + AND Ant + so that it both turns the amp on and raises the antenna?
