Posting this for a friend who is not computer literate, but is as much a hot rodder as any of us. The pickup is a '64 Chev. Truck is one he's installed an OD Chev. trans., a late model 3 spped synchro 1st gear, but Borg Warner od controls are pretty much the same all the way back. Book says hook kickdown wire to negative side of coil in order to interrupt power to allow od to kick down. But an HEI ignition has no "negative wire" on the coil. He asked me to do some research for a solution, so here I am, checking in and asking the biggest data bank I know of for some help.
