Heater Help - how to connect hoses to engine

[sportnautiquekim]

We have a 1993 Sport Nautique, and just bought a heater by heatercraft. Cannot find in manual how to connect hoses to engine. We have a 285 HP, 351 PCM Ford Block, Holley 4 Barrel Carb (not fuel injected). Looking for some expert Nautique folks for advice.

The instrucions say to T off of the temperature sensor at the top of the block and return to the block on the side with the knock sensor or get a low speed return which goes into the raw water hose before the raw water pump. There are pictures somewhere on this site if you search.
