I remember back in high school 23 yrs ago, a coworker wired up a variable speed switch to blow heat but that's been removed. I noticed an orange wire with a boot on the firewall that wasn't plugged in. I tried that. but it didn't make anything work. Here's pics of where I'm at. You'll see the orange wire that's not plugged in just off the center of the photo.
