Stereo. The car came with a very much too modern head unit and speakers which cut in and out and crackled when you hit bumps. When I was in with the drivers window I found some choc-block goodness, so had those out for uninsulated crimps.
That was going to the cross over, I then found some more choc blocks between cross overs and drivers, including one that was screwed down on the insulation that was probably causing the issue. The passenger side kept jumping out of the door, which turned out to be the crossover double sided trim taped to the door card and pulling the mounting out. Fixed that up too and isnt how I've ever done tweeter installs in a 300 before, but works fairly well.
Gauge time. I had a spare 6 dial dash, so popped out the ambient temp and econ and transferred those to the cars dashboard.
Along with the temp sender. Wired bundled and taped under dash as expected of a late 340, I had a spare dashboard to bumper trumpet loom and sender.
Then gauge panel. I've never come up with a solution I'm happy with for gauges in a 300.
Kar had 3 in the stereo aperture (Oil press, oil temp, voltage).
Fake had a 440 dash pod in an MDF mount in front of the gearstick (where the genuine panel is, but I insisted I wanted to keep that as I put my phone there whilst driving) with Oil press, voltage and narrow band lamda (having decided oil temp was pretty redundant, you can use it once to see what temperature you get to, but after that you can tell when the oil is hot from idle oil pressure)
Having driven over 100,000 miles in "not 300's" since Fake was written off, mainly in an S60 and mk1 MX5, I've got over the wanting to keep the pocket in front of the gearstick. Both the MX5 and the S60 don't have anything as usable as a 340 door pocket, so that is now plenty. That feels like time to have a genuine gauge panel then. A bit of amusing facebook trading (a three way swap between a 3D printed carb trumpet, a Volvo 5 bar oil pressure gauge and a gauge panel) ensued, then I realised I still needed a 5 bar gauge. I have several 3 bar ones... Anyway, that solved, onto fitting.
I've seen several gauge panels that never seemed to fit right so went to the blue leaflet section of the forum that shows the gauge panel when new comes with 2 clips to fit it to the gearstick surround. I obviously had no clips.

So, armed with just that drawing, I went over to the CAD and 3D printer (I only got it just before Xmas and it's great for this sort of stuff) and made some clips. I did find someone with some genuine ones later, which look nothing like the blue book diagram

Fits ok
Lining up against a flat edge. I used a couple of euro cent coins to space the panel correctly. I couldn't use the blue leaflet template as no idea if my clips had the same centre line!
Panel wasn't perfect, but not at all bad. The wavy top can't be see from the car and the random LEDs may come in handy one day. They have been done neatly, but the legs cut off...
Whilst I was creating the wiring loom for the gauges, I looked to replace the bulbs in the ashtray and cigar lighter (I needed the cigar lighter out to get dash illumination to the gauges, I also put the pin in to the stock stereo connector whilst I was there. The crimp terminal required is TE CONNECTIVITY / AMP - 925663-1 if anyone ever wants to add that, wire colour should be blue with red trace)
Bulb was fine in the cigar lighter, but the bulb holder earth had oxidised. To give a clue of how little earth there is....
Untaped partial loom
And the stereo illumination if required goes in this hole in the plug (shown before crimping)
