I have the same setup, if you are still stuck on this PM me with your email or contact info and I can try and send you a video or some pictures of how I have mine plumbed. But the long and short of it is I have it as follows;

[Coolant comes off the top of the block>>>>coolant inlet of center chra section>>>>>coolant outlet of center chra section>>>>barb of the XT cooler that is located further towards the driver side>>>>exits XT cooler back into the throttle body barb].
