I want to put the original KM speedo face back on my W126 euro car. I can get the panel out just fine, but when I look back there, there are tons of wires. Is unhooking all that and hooking it back up something a DIYer can do or should I leave this to a pro? Also, were exactly is the temperature readout "box" when looking at the back of the panel, I need a new readout. Thanks for any help.
