DIY electric fan controller

[83gt351w]

After researching fan controllers, I’ve decided against spending 200 bucks on one. So I went to the junk yard, and pulled a temp switch out of a mid 90’s BMW, which was located on the pass side of the radiator. I also pulled a 2 spd fan relay out of a mid 90’s Volvo which is located under the pass side headlight. Then I tapped my thermostat housing to accept the temp switch, which is a 14mm x 1.5. Follow along as I attempt to get this baby working.
