Wiring Harness Routing

[BruiserOutdoors]

Looking for ideas of where and how to route Pro Flo 4 wiring/ecu and 4r70w US Quick 4 harness. Ideally I would like to hide the ECU behind the glove box and the Quick 4 Controller in a under dash cubby or in the glovebox. I am hesitant and unsure how to get the wiring through the firewall in a clean manner. Photos and advice are appreciated.

Hard to see in pic, but ecu is mounted on plate on the center of fire wall, transmission is shift module was ran into center console, there is a lot of wire with the us shift unit.
