Electric fan wiring question
I have a question regarding the wiring of an electric fan for a cj5 with a 258. The question is regarding the thermostatic switch. I have two options and need a recommendation:
1- wire the fan using a thermostatic switch threaded into the cooling system (negative trigger through relays) or
2- using thermostatic switch that pushes a probe into the fins of the radiator.
I know how to wire each, but I am not sure which route I should take. Any suggestions would be greatly appreciated.
