advice on EWP (Electric water pump) setup

I wanted to confirm a few things for my EWP (Electric water pump) setup that I'm planning on running. I want to run a similar setup to Neutron in this thread. My Setup is for a 13b REW on a haltech R3 ecu, I deleted the AC but I'm keeping power steering. I'm having trouble finding a side mounted alternator bracket; any recommendations would be appreciated. Does a bracket exist that allows me to side mount the alternator, run EWP, and keep power steering?

The list of parts with links:

Meziere water pump

jdl water adapter

Haltech SSR (Solid State Relay) I think this is all I need to control the water pump with the R3 but would need confirmation on this.

Built 2 Apex used to make em. Gave me 25% off future purchases because it was late as hell....now they're closed.
There's some shops in Australia and New Zealand that are making them now though - Franklin Performance and Billet Rotary

I had a meziere ewp on my Ls and burned through 3 of them in a year and threw the stocker back on. If you really want a real ewp that actually works you need to get one of these pierburgs, theyre like a fire hose and can be controlled with a pwm style controller

I've heard good things about Pierburg CWA water pumps from people doing EV swaps. One of the challenges is picking a cooling pump that can flow well against pressure, and it sounds like the Pierburg ones do a good job at this. I've seen it's common to switch to AN fittings instead of traditional hoses, but I think it adds a lot of cost without much gain. I think the factory radiator hoses are pretty large to start with, and it seems there isn't always enough space to fit a big AN wrench near the water pump inlet on the front iron.

The one thing I did like about the meziere pump was the built in thermostat, which will aid with warm up times and not cause any over cooling issues. Is there a clean solution to utilize a thermostat with the Pierburgs CWA pumps? I know this thread exists, but I wanted to know if there was a newer method for utilizing a thermostat with an EWP.

I was looking at the Franklin Performance side mount but they require a 12a cover and it also deletes the Power steering. I’ve been contacting different companies to see if they can custom make something.
