6. Cylinder duster is now a 340 ignition issues wants to start when you let up on the key

Thanks again.... I wonder if there's a diagram that shows the engine harness plug that goes across the intake. Looks like it feeds the temperature sensor and wires to the alternator. Not sure what else
yes @67Dart273 posted it in the same thread.
This post.

Use that with the diagram.
J3 is ignition start and also the connection to coil
J2 is ignition run
G something are the gages
C I don't remember but you'll find it or figure it out.
S relates to the starter relay
