Got the IR sorted, just desoldered and extended the one on the STB, prob hide it inside a vent on the dash. Just going to drop them in the rear left 1/4 panel, prob just have them loose, wrapped in foam, they fit quite snug, but have to allow enough ventilation. Havnt been able to find a signal wire to turn the boxes on only when VTR2 is selected, so prob have them wired with ACC.
