2007 Yukon died while driving. Found harness unplugged but cannot find where it plugs into!

That's the connector for the suspension control module which is above the spare tire..yes it can cause the truck not to start.Maybe the module fell out? Please excuse my Jersey shore frame rust.

if the module is missing, there's 2 wires you can jump to complete the can. should allow you to drive the truck.

Does anyone have a definitive location of where the Suspension Control Mod would be?

Directly above the spare tire. If you do not intend on keeping the air ride you can by bypass the connector and splice the wires directly. I believe the low speed can runs through the module and most likely shorted out from some corrosion in the connector. You gotta verify though.

Seems to me that if the suspension module has been missing for a while it doesn't explain why the truck died now. Unless the module somehow just left the building or was disconnected by the jolt, physically-speaking.

Are you sure it's not up there hidden by the frame member, having slipped out of one of the keyholes? What's in the keyhole that I've circled in the pic below?

Here's the bypass video if you need to do that. I'm thinking that if the module has been missing for some time, something like this may have already been done.

You could fix the suspension yourself by ordering the parts from Rockauto and save yourself some money.

Ok, 07 Denali. Not sure if truck is standard or XL. Someone posted that suspension control module may be under rear seat on standard trucks.

I’m dizzy looking at the pics under the truck . Since the truck is still under warranty from the $1.8k dealership repair last month, call them and tell them what happened. It could be a no charge, call back repair they need to handle.
