I think its to oil cooler on the side of the motor under the turbo. Well they say i have to relocate that for twins but where do i put it? And if i move it how do all the lines hook back up do i just get longer rubber lines or something.

 

iirc i dont think you have to. just flip the exhaust manifold upside down. idk tho hopefully someone will jump in..

 

That is the transmission oil cooler, or heater.
I is hard to get the lines off and hard to unmount.
Good luck

 

On auto trucks, with twins, you usually have to relocate or eliminate the tranny oil cooler, the fluid still travels through another cooler, and you dont have to relocate your oil filter but it is recomended, the twins usually rub the filter, if you do this, i know pacbrake sells a relocation kit for your oil filter, it comes with everything you need to install it including longer turbo feed lines.
