Round is for lighting others are just engine plugs for sensors/gauges reading from the ddec ecm.

You can ohm test from the gauge outputs to the pins at the plug to figure out which one is which.

I went with mechanical gauges and swapped em out and then just wired the switch thru the fuel solenoid and starter etc.
