Offroad-Express

Have got a cooler to put in and am just wondering what line is the feed line to the factory one? The one on the left when looking from frount of truck or the right, just want to make sure i put it in before it goes threw radiator cooler

its messey, but just run both lines into buckets and start it.. that'll show ya which is the feed

^^^^ Thats how I do it as well.

From memory the front outlet from the trans is fluid out

i done some research into this as ive just installed trans cooler, the front (higher pipe) with the sensor plug on the trans seemed to be the out, and the back (lower pipe) seemed to be the return, ive hooked mine up this way and all is working fine.
