Sorry we did kind of get off track.
It looks like the plugs you point out might work.
There was also device made back in the 60s by chrysler that used the variable guage sender output to trigger a warning light. There might be a modern equivalent.
I agree, u can get Mopar sending units for the lights that will screw right into those ports. Sending units for a gauge are different so make sure u get the right ones. Kim
