Good stuff so far Jeff.
One minor point - British aircraft did not have the yellow tape around the blind flying instrument panel. This was an addition to USAAF fighters in the ETO, to highlight the instruments for easier concentration in the poor European weather. The last remaining Hawker Typhoon (currently in Canada) has the yellow tape, but only because it was loaned to the US, for evaluation, during WW2.
For the IFF wires, you'll find that 'invisible' thread is ideal in this scale, and can be attached with a tiny spot of 'superglue', to the small hole, after adding the decals and final clear coat. The 'tail end' can be fitted in a similar fashion, either to a very small notch in the tail plane, or a tiny hole, and any small imperfections can then be re-touched with a fine brush.
The 'invisible' thread is available in a number of shades, including a 'smoke' colour, ideal for the wires, and can be found in haberdashery or needlework shops.
I've included a couple of pics of the attachment points on the real aircraft, taken recently at Duxford.
