the blue wire does go dead when you turn the key to crank & juice flows back thru the ballast over to the blue wire side then out to the ECU as it too needs to be fed in "crank". If you go with an ECU (HEI) and an E coil & both are designed for full on 12V (no ballast) then yes you would T the blue and brown wires together then when it starts you also have current in the brown wire circuit from the blue wire cuz they are tied together but it (the brown wire) dead ends back at the ign sw "ign2" terminal & there's no problems with that. The Carbonaro effect is on so I will check back tomorrow
