Question: Ignition and T4 universal wiring kit
large yellow wire to the ignition run/accessory terminal then link it to the red wire to the battery.
What does "link it" mean?
My guess is they have a relay in their harness and the yellow wire just actuates the relay coil. The red wire goes to BATT+ (always hot). Without a ballast, you should tie IGN1 & IGN2 together. When people use their factory harness w/ HEI, they usually just jumper the two terminals that went to the ballast. Sounds like you need to jumper similarly, but perhaps under the dash. If you don't, your ignition won't get power while cranking (i.e. no spark), since only IGN2 is powered in that position. I found that out the hard way with my custom engine harness. I had ASSumed that IGN1 got power in both "run" and "crank" positions.
If doing the jumpering at the key switch, remove the IGN1 & IGN2 terminals (release w/ small screwdriver) and fabricate a little jumper harness, using new "Packard 56" terminals (GM & Mopar). You could also use the crappy, unreliable clip-on taps, but sounds like you care about your car.
If for some reason you require a new ignition switch, I recall buying a new one for my 65 Dart for ~$10 (rockauto).
