Make sure you have plenty of slack in this wire. The pickup is mounted on a plate inside the dist that moves with the vacuum advance and the centrifugal weights inside, that's how it advances and retards the timing. So this wire is flexing continually, and is usually a special type wire like meter lead wire. Knowing the way parts are made now, they may be using inferior type wire, and like I said, make sure there is slack enough for the wire to move with the plate.
