All good advise! For some additional detail, the backside of the X-1's instrument panel
is visible through the canopy. The instrument cases are represented there and should be painted flat black. You could also make up a wiring harness by driling a small hole
in the back of the case and use fine wire for the instrument wiring. This should be routed to the left and into the from edge of the large junction box on the left side of the
cockpit. For the real fanatic, small pieces of sprue could be glued to the back of each instrument to show the cannon plugs. Drill the hole for the wire in those. Cannon plugs
are usually silver or OD green. The wiring is usually white.
