ClusterTruck; because that’s what it is

I needed to mount my LS fuse box, and wanted it to look factory-ish. I thought about closing in the bottom fully, but decided keeping it open fit the vibe better and gives some access.

Now for some AC parts. My harness came from the deliverance dude and looked pretty decent. Seems it had spent some time outside tho. The relay had no continuity when I tested it.
Time for a relay upgrade since these just work and I have lots of them.

I wanted to add a heater core shut off valve but wanted to maintain the LS bypass. Some research led me to this setup. It fits well and should work.
The hard line and some T’s are from the 4wd actuator circuit off a 2013ish 5.4 Expedition. Plenty of those in the junkyard.
I used a little heat from a lighter to get the bends in the vacuum line. It’s teed into the same circuit that actuates the cowl flaps for recirc.
