its a s2 with efi engine, ive got my engine back in the car and nt sure where some pipes go,on the mfi setup the two pipes that come out of the oil cooler go into the two outlets on the inlet manifold but the efi inlet only has 1 outlet do i need to join the pipes together or blank 1 off?????

 

I cant be 100% shure but if i remember correctly the tee connetion on the main water pipe goes into one side of the oil cooler (so connect up the two pipes as you said) and the the other side of the oil cooler goes to the inlet manifold.
