What exactly are you trying to figure out? I see your jack, your heater box, and some wires and stuff. If you want to know about specific wires or hoses, please point to/circle them in the pictures, or at the very least describe what we're looking at here. The pictures don't even look like the same truck, the ones with the jack pictured, some of them have wires/ hoses in the pics that aren't present in some of the other pictures. I'd be more than happy to help, but I'm honestly not sure what you're even talking about.

I will try and take better pics but by the jack there is a huge harness by the brake booster,same side there is the single plug wrapped up. Heater box side there is one wrapped up by the box.
I will get better pics just wondering if anyone has any ideas before I head there and thanks

What carb,what engine, what year truck are you running? That would help with correct egr routing. Generic would be ported vacuum to a TVS to the EGR valve. More generic would be ported vacuum to EGR valve.

I am not entirely sure, it's an 87 suburban, originally a 6.2 and at some swapped to a 350, guessing definitely has a q-jet, when I get back I will definitely take better pictures.
Thanks

I'm guessing the vacuum line was for the cruise control.
Thanks

That looped up bundle of wires looked like the knock sensor connector that was on my 81, 305 V8. mine was just above the oil pan on the block on the passenger side.

There is a hint on post #4, you have some extra 6.2 diesel wires floating around.
