First off a little back ground. Its an 02 5.3 going in an 84 c10. I got it today and it has some stuff missing. Just trying to get loose ends tied up. Im a newb to ls engines so please be patient with me. and thanks in advance for any help.

First off, what sensor is this (cam/crank maybe?) and what goes in the hole next to it?



Second, im guessing this is a coolant crossover for part of the EGR (wont be running egr) where do i need to redirect it to? or can i just cap it?



Third, what is this?



Fourth, what are these bolt holes above the manifolds for?





Oh yea im also going to need all front accessories and brackets so if anyone has any they want to sell please p.m. me.

 

Pic 1- oil press sensor, cam sensor goes in the hole next to it.
Pic 2- Connects back to the rad
Pic 3- Oil is routed behind there, that style cover can be drilled and tapped for a press gauge or oil feed supply.
Pic 4- Holes not used on my trucks.

 

Thanks man. was begining to think no-one knew.
