I have a small 5"x10" transmission cooler (12k gvwr) that I plan on running in line with the factory one and want to mount in the fender wall because it has 4 5x5 fans so I won't need airflow, and that I want to keep out of the elements (1.44amps total, so about 20watts, won't need a relay).
IIRC from the radio install, the 04+ doesn't have a switched 12V line for accessories right? Should I wire them to come on with the radiator fans, or is there a switched 12V line under the hood that I can tap into, such as the running lights, that won't bother anything?
