Flipped the body of the donor 2007 Aspen off the frame and put the frame into the garage.
Pulled the engine and returned frame outside.
Tested the Hotwire harness. MAP sensor plug too short, AC, and alternator plugs too long. Quick note to Chris Squier at Hotwire got me a same day build on an extension wire for the MAP circuit. Should ship today.
Ordered 3 extra feet of harness so fuse box, relays, and PCM can mount under dash below glovebox.
I will mount up transmission, starter, and fuel pump for a test start before I commit to pulling 440 from Cubicle.
