I’m putting together a mid 80’s 454 and I’m having trouble figuring out how the water lines run. Anyone that can tell me were to get a diagram?

If you click on the link below you'll see a picture or 2 of a PCM 454 showing most of the lines. (Ignore any bickering you might encounter, or have fun reading it, your choice  )And this Hollywood diagram shows how the inlet and outlet for the RWP hook up on a RR 454. if it happens to be a normal rotation 454, then the hoses would be swapped around on the pump  |

I did learn a little bit from that. Ty
But I can’t tell where the hoses go under the motor. The hose from the inlet must go to the the tabby cooler first then to the inlet on the pump? The big hose coming off the thermostat housing goes down under the motor but where does it go from there? |

The big hose goes to the circulating water pump suction
And like you said, inlet fitting to transmission cooler to RWP suction. And you can't see the rinky dink little 90 degree hose in the pictures that goes from the circulating pump to the intake manifold.
