I am installing a diff cooler with electric pump (cooler will be located in rr brake duct) .
My question is when filling the diff normally you fill it to the top of the fill hole how much more do you add to account for the cooler and what is the correct fill method .

I appreciate any help on this thanks!

Why not fill the diff normally, then put the plug back in. Start the pump so that it will suck the fluid up into the cooler and disburse it in the lines. Turn the pump off. Open the fill hole again and top it off. That should fill everything as necessary.

Makes sense thanks Falcon, appreciate it.

I agree with Falcon. That is the proper way to do the filling process with a cooler.
