Hi All,

Thanks to all that have come before me.
Ive read this post from end to end - TWICE.
Ive got everthing in hand or on order to complete this conversion on my '02 LX with ML audio.

One question that I need clarification on:

Will the Metra Harness

Metra 70-8113​

enable me to use the ML Amp / speakers?

The OP @primeral said it worked for his but others seem to report problems then end up changing out the amp / speakers later.
I'm going to verify my amp works before starting. Then, after the new headunit install if it still works re-foam all my ML speakers.

Appreciate the input. (Especially if the Metra harness worked for you!)

UPDATE -
The non nav bezel went in without issue. Followed the pinout guide and all functions are 100%.

PROBLEM -
As I feared the head unit is powering on and functioning normally hower, NO AUDIO output using the METRA 70-8113 harnss. Amp audio output was working before and is powering on now (Fan activates with IGN switch).

Ive seen others post that the METRA TYTO-01 works for the ML amp although its listed as JBL compatible...
Im hesitant to order it for $89 if I cant confirm it works?

HELP! -
Any Mud members resolved this issue without replacing amp / speakers?
In the meantime Im gonna call Crutchfield tech support although I doubt that will get me anywhere.

Hey did you ever get this figured out? I think I’m in the exact same spot. Can confirm the speakers worked through a Grom unit before the swap. Everything is swapped and functional except no audio out of new head unit
 
It is done! I’ve been prepping and planning to do this swap for a few months now and I finally have it completed. My swap was on a 2002 LX with ML. The new climate bezel came out of a 2001 LC.

It’s really not that hard, just pay attention to what you’re doing, be gentle, and take your time. I followed the pin out guides posted in this thread. All of the wires matched up for me fine, except for 1 or 2. Everything climate related worked first try except the illumination which I didn’t realize until a few days later. The pinout guide I used didn’t have the wires for illumination matched up so I skipped them, there is a different pinout guide that does have those wires. I went in and fixed it with the latter guide, took no time at all. I labeled all of the wires on the new pig tails with their number and what they connected to. Then I went and labeled all of the wires on the vehicle with just their number. Color coordination makes this a breeze, however, I only thought of that after I labeled the new pig tails lol. I just sat in there with a printed pin out guide and marked them as I went. Simple stuff

The biggest issue I had was getting audio to play out of the new head unit. I bought the head unit from crutchfield with the Metra 70-8113 harness adapter. It didn’t work, I probably could’ve made it work but instead I said screw it and installed a fully new sound system.

For the new sound system I went with Polk DB6502 components, a recoil DI550.4 amp, and a 10” kicker down firing sub. The door speakers mounted up with the mounting plates fine and had plenty of room. The tweeters required a tiny bit of modification, if you can do the rest of the project you will have no issues getting the tweeters mounted. Just trim the housing and cut off a little metal piece from the stock bracket, add some 3M double sided tape and boom there you go. The amp and crossovers also fit with lots of room to spare.

I tried to use the stock speaker wire for the new sound system, and it worked for the passenger door, but not the driver door. I figured it was the nav computer harness but I cut it and spliced the wires and it still didn’t work. I just ran speaker wire to that door. As I’m writing this I’m thinking of possible solutions that might’ve worked but hey hindsight is 20/20 lol.

I didn’t mess with the rear doors. 1. Because I don’t sit back there and 2. Extra cost. I may add them in the future but I would need to get another amp to run my sub.

All in all it took me about two weekends to get this completed. I did the actual nav swap in one day. I will miss my wood trim bezel a lot but the added functionality is amazing. If anyone has questions feel free to comment or dm me!

10-1-2022 edit: I relinked some deprecated pics and I'm self-hosting the spreadsheet.

Here is the link to my spreadsheet in PD
Does anyone have a link to the wiring diagram? I just order a non nav dash with pig tails and looking to make the conversion in a couple weeks.
F and XLSX formats.
Another update: print your own radio bezel. I modeled it in CAD and it's a free download.

Thanks to redjet for his original spreadsheet which mine is based off of. I mapped all pertinent pins for anyone to easily follow. My vehicle is a 2001 LX470 with Mark Levinson audio (North American LHD model specifically).

The relevant connectors are at the back of the AC Amplifier and the orange plug at the AC/Nav fascia. You will label the matching plugs on your harness I, H, F, G, and E. (I didn't order them that way, that's how the Toyota wiring diagram identifies them.) Also note the 20-pin connector at the audio control unit, it's a perfect match for the Metra 70-8113 harness.

This is skipping to the end-goal, but this is a picture of the double-DIN radio bezel you can download and print.
