I removed all the AC components from my 1986 C10 and added an aftermarket AC delete plate.
My resistor was bad so I purchased a NON AC one (much shorter and lower profile), but noticed there is only 3 male ends on the resistor as compared to the AC resistor which has 4. Can I use the NON AC resistor and if the answer is yes, then what is the wire setup and what is this extra wire on the AC resistor plug???
Lastly, do I really need to run the rubber 3/4" hose from the back of the blower motor to the AC delete box???
