Identify These Wires...
Completing an LS1 swap in my '93, but over time I need help figuring out which wires these are. I know one is oil pressure. If you know that wire/plug post it up. 
The first 2 pics are the same wire, it has a thick brown sheath... I believe the 3rd pic is oil pressure, and I'm not sure what the 4th pic is in post #2.

IF #4 is Y-G, it is most likely the temperature gauge sensor.
IF #3 is Y-B, is is most likely the oil pressure sensor. [edit: Y-L: "Yellow-Blue"]
#1 shows a home-made splice, so all bets are off. The wire to the connector looks like it's "grease-colored," but since it's spliced on the real color might not matter.
#2 looks a little like it might be a wire shield, so depending on WHERE the wire is in the harness it might be the knock sensor.
These are nice pictures of your hands. Of the wires, not so nice. Except for spliced wires, a lot of wires can be identified by color. YOU can see the color easily enough, but it's a tougher for someone else to squint at a distant photo with iffy color-balance.

#1- It does look like a Jerry rig like scope said, but if it is black and fairly thick it looks like the knock sensor wire (if it used to run under/through the intake plenum, right below the injector wires) it's the knock sensor
#2- If it's brown with a brown clip, it looks like a starter wire; if black, then knock sensor (thanks again scope)
#3 & #4 (YET AGAIN, THANKS SCOPE!) they are oil pressure sender and temperature sensor
