where does this water hose go
 

water hose hooked to a port sticking out on the top side the water pump body. The port faces towards the rear, it snakes down and over to a hard line up in the middle of the bay, where does this end connect to?
thanks

It appears to be throttle body cooling lines I guess

yup, hardline feeds to underneath the TB, then moves from the rear of the TB down to the rear iron. We delete the TB coolant on most modified/performance builds at the shop.
