Hi all, just bought this 2007 Sierra 2500hd 6.0L, 6L90/2wd truck. The PO has a "cold" air intake from the wrong truck/car on it but what's really stumping me is what this is? (see pic) There's 6 wires that are just sitting there bare, no connector in site. It's the same harness on the passenger side of the motor that has the fuel injector plugs in it. The stock intake is long gone, not sure if there was any sensors or anything in there that this went to besides the MAF?
