Help! What's the feed side?

I can do most things, but I'm electronically dyslexic, so can anyone tell me what's the "feed" side on my 70 B body ballast resister (I haven't got the ignition switch and main bulkhead plug wired in, so I can't switch it on at the moment to put a gauge on it).

I've got one blue wire going in one side and two wires, brown and blue, going into the other.

If I can sort that out I can finish the electronic ignition and engine harness and fire it up!

The single blue is the feed, the other blue is the 'output' from the ballest and the brown goes to this wire and is a 12v on crank wire to supply 12v to the coil to aid starting rather than the ballested voltage the blue wire supplies

Three minutes flat! But then you were always quick off the line weren't you Alex?

Top man, thanks mate!

For reference, the single blue comes from 'I' on the volt reg, terminal 'N' on the bulkhead plug and the field terminal of the alternator.

the other blue goes to the coil +ve

the brown comes from terminal Q on the bulkhead plug

Sorry Steve, only just found your post.

I'll see if I can record it with my digi camera, which has a movie option on it.

Everything's done engine compartment wise, but I think I'll wire the dash and ignition switch in first.
