Thanks all!
Richard, are the orange/white wires in the bomb tail all live (ignition on)? were they designed into the loom for whatever car it was originally designed for? If I have understood that correctly then I like the idea of a readily available live feed. Would it then be alright to fit an inline fuse. I'm sure both items have a negligible current draw, what would you suggest fuse wise, 5A or below?
Yes as mentioned above all the white/orange wires comprising the bomb tail distribution point are fed by same colour wire from "run" position on ignition switch. An extra inline 5 amp fuse for a connection here would be fine.
Note tapping into the radio switched feed (light green/white wire) would be ok bearing in mind it's fed from the first "accessory" position on ignition switch which obviously remains live when "run" is selected. This feed runs through 10 amp fuse 9 for radio and horn.
