Glad you're enjoying it! Need to link up sometime now that I'm up here in the high desert. I got the front door "weathershields" from OCAM4x4 when I got my mirrors.
Weathershields For Toyota Landcruiser 70 75 78 Series, Up to 2006 Front 2pcs Window Visors - https://www.ocamindustries.com.au/weathershields-for-toyota-landcruiser-70-series-up-to-2006-2-pcs
I haven't put in my rear camera yet. Was waiting until I did the rooftop conversion, then will probably put it up high like a sprinter so I have a top down view. Will need to splice into my reverse lights for sure! I had to tap into them already when I installed my rear bumper as the tire swingout now blocks the OEM brake light on the passenger side.
The Alu-Innovations pop top also has a rear brake light up top above the rear doors, so will need to wire that in as well.
I'd been trying to figure out how exactly to wire in the "reverse switch" so my head unit auto converts, but hopefully mine also works with taping into the reverse lights.
