Another starting problem

67Dart273;

“backfeed” was the word I was looking for.
I jumped 12v from the battery to the IGN1 side of the ballast and it started right up and ran.
And wouldn’t cut off! Oh yea, the jumper!

Apparently the load in the IGN1 side is pulling the voltage down.
I the DkBlu goes to pin 1 of the instrument cluster.
what does that go to?
