Help me identify these two sensors.

Also in that area where the starter goes, not sure if there is suposed to be a plug in there or a plug in the front driver side of the block. I only have one plug left and both spots have the same thread but I don't know what they are for.
By the starter(has the plug in it):


And then by the front driverside of block:

Does that get a plug, sensor or nothing?
Thanks for any info you guys can give me. I'm getting real close to firing this thing up, after this just the tranny left.
the short on is your crank position sensor which goes in that hole above the starter
the third threaded hole i don't have a damn clue
You need the threaded plug in both places, the one in the RR is right where the crank sensor goes.
The threaded hole in the left front is an oil galley, you can leave it open if you want 6qts of oil on the floor in about 10 seconds after you start it
That's perfect that the one is the crank sensor(the only one I knew I was missing) and the other is the cam sensor which makes sence because I already replaced that with the new ls2 set-up.
kp,
Your saying I need to plug both the hole in the rear right, where I have the plug now and I will need to plug that hole in the front? That means I must have used one of the other plugs in the wrong spot. The lsx block came with plugs but only showed where to put the 4 big ones, two in front of the block and two in the back of the block, that was a no brainer because they are the only holes that size lol.. The rest I've been trying to figure out. I'll have to go over them again and see if I can figure out why I'm missing a plug.

Maybe they just shorted you a plug..
