What about the power supply to the gauge cluster? The gauges are LED also but I dont want to tempt the Chrysler wiring. I'll tap into the switch panel light wires for my LED bulbs that cut on with the headlight switch.

If it's heating up while idling, likely the fan clutch.
If while driving, it has to do with coolant flow and/or air flow. Passages in the radiator can become blocked (common), and block passages could be restricted.
Fins on radiator and condenser get blocked with bugs and grit/sand, limiting airflow. I blast them with compressed air occasionally, from the inside out.
Have to cover ALL the bases when it come to this cooling system.lol

Either saves gas or wastes it, depending on your perspective...Now that's good advice.

One step ahead of you salad lol. You spotted my blonde moment though (and im gray) because I had forgotten I did that. I've switched all my gauge bulbs to LEDs. So should the stock gauge supply wire hold up to two LED gauges?

For sure. Most LEDs draw 1/10th of their incandescent equivalent (if that)

last question for a while, Is the reason for lack of space in engine compartments in everything newer than 1970s, I guess, due to aerodynamic improvements?

Are you talking about the resistor?

What resistor is this that gets hot? For record, kick panel lights are LEDs now too. Need to convert the top two roof lights then everything save for the switch panel/HVAC panel will be LED, and those will be soon to follow.
