I'm wiring up my new MSD 6AL box and it says to connect the red wire to the ignition wire after the switch not the in coming 12v side. I have some old 1970 wiring diagrams and from what I gather its the solid yellow wire. Does this sound right or does anyone know for sure? I almost connected it to the 12v side coming from the solenoid! Just for info I'm also running a Mallory comp 9000 distributor.
