Decided to try a first fit in situ of the panel which is just as well as I had managed to put the Master cut off switch a fraction too close to the centre panel, forcing a slight re-positioning.
Its now case of picking up the various numbered tail end leads and connecting them both at the ‘sharp end’ (engine CHT, EGT etc) and panel end (terminating at the ‘D’ plugs of the MGL Infinity unit.
