Hey guys,

Sorry for the bombardment of questions as of late, just running into some minor snags.

The latest one is the electric fan hookup. Is there a quick way to hook them up or do I have to go out and buy a temp sensor and relay?

hook it to a switch. hook the switch inline with the ground wire and hook the positive as a constant into the main batt lead.

use a relay if you have powerful fans, then you can use a smaller / prettier switch.
