    ignition switch source for fuel pump relay kit?

    i know i know i see it emphasized all the time, unfortunately when i did vortec heads, i ended up with a comp cam camshaft upgrade that does not support mech fuel pump (missing the fuel pump lobe) so we used a blck off plate for the old mech fuel pump location on the non vortec block. the kit...
