msd help

[69projectKAOS]

i have a msd street fire ignition and i have everything hooked up fine but this one small red wire that says it should go to a "key connector" or heavy red or pink wire from cars wire harness. where is this on a 69 camaro. or is there somewhere else i can splice this wire into???

i have a HEI 4-pinn module (magnetic pickup trigger)

on my 69 i hooked my msd to the two wires that are tied together and went to plus side of factory coil

i dont have a coil in my 69, so should i put that red wire to the plus side of the distributor?
