I am in a middle of putting a 6.2 liter Diesel engine in my 81 K5. The engine came from a Navy vehicle wich was used to tow airplanes (with ultra low gearing). I have taken out the old harness for my carburated 350 and lot of the wires where not connected to anything (was probably connected to some smog stuff or the AC wich has been removed long before I got the truck). Now I am trying to clean out my engine bay was wondering what this is: 1: I have the harness from the navy vehicle but am not sure what everything is (even though I have my guesses). It would be great if someone could clear that out for me (both on the top of the stearing tube). 2: 3: Even though I am not sure, I think this is not from GM. My guess is it was put in when they converted the truck to this machine. 4: Somebody have cut this thing I dont have the slightest idea what it was connected to: 5: http://www.f4x4.is/new/photoalbum/?file=cars/3734/24622 And last, this was in my K5 and I think its connected to the interior lights. 6: It would be great if anybody knows anything about those items, thanks, Jon H.
