I ended up choosing function over form and went with a Sony CarPlay head unit instead of a Blaupunkt/period correct deck. This one just got discontinued but has a capacitive screen. The new version is identical but just adds an HDMI port, which I don't need.
I would have liked a volume knob but those are few and far between these days. This at least has physical volume buttons.
OEM brackets go right on -
Picked up the Metra 70-1761 harness that bypasses the factory amp. From here it's a simple job of lining up the colors and connecting the wires.
I left the power antenna and backup camera wires disconnected. For the green parking brake wire I'll cut that down and add a ring connector to ground it to the chassis.
This unit has wired CarPlay so I added a USB charger/CarPlay pass through combo charger in place of the cigarette lighter:
I also added a CDL switch as you can see in the upper right hand corner of that last pic. I did the "Pin 7 Mod" as well.
The ABS module on the HDJ81 is on the right side of the car, next to the accelerator pedal. I know this is well documented on Mud for LHD FZJ80s but here are a few pics.
I followed the Slee directions here:
This modification does not have anything to do with the CENTER DIFFERENTIAL LOCK SWITCH (CDL) directly. You do not have to do this, if you just install a CDL

Remove the silver ABS module/bracket up above the accelerator pedal:
Once it's moved out of the way you have access to the Transmission Relay with the plug we'll be modifying.
Pull pin 7, the black wire with a blue stripe.
Taped up and good to go. Reassemble.
