Oh, that is a good job there!
I went through this here recently. I ended up getting the universal pump and mounting it to the side of the original reservoir bracket. I like how it turned out but I still have to wire it up and run the hoses.
Can you post pics of how you wired it so that it worked with the original dash controls?
Why do you not like the universal pumps? I have never used one so I do not know anything about them.
Here is what I have so far. I intend to run the wiring behind and below the bracket, inside plastic auto conduit, and attached to the inner fender, hooking up so that I can use the original dash control. The hose will go inside the outer fender. I have the original squirter nozzles.
