Kerry,
Just went and checked my '02 L/C td ute, and the heater hose comes from the passenger side, at the rear of
the block, up to the water metering valve, then disappears via a short hose, into the fire wall.
Would suggest you fit your heat exchange unit between
the block and w/m valve. Water will flow through the heat exchanger, towards the valve, and into the heater, and back to the engine(on driver's side) when you adjust the heat control, in the cab.
The tricky part is finding an ideal position for the H/E, and having the right hoses/bends for the fit.

On 1HZ engine

Bend & Fittings

Different H/Exchange Unit.
The above are some photos I scored off the net, to act as a reference for fitting. The other thing to remember is(and I got this bit of advice off this
forum) to have the flow of your shower water in the opposite direction to the engine coolant flow.
Bob.
