So I have the basic setup of the control panel and now I tolt it over under the hood and place it above the motor/transmission.
The rear of the panel will pivot on 2, half inch bolts and the front rests on a horizontal bar and bolts there in the center.

So the final outlay here is the controller on the vehicle’s right, electric box #1 center and rear, box #2 center and forward, DC/DC on the left, cooling fan under the controller, large Anderson connectors SBX-350 (144 volt) under DC/DC twards the rear, small Anderson Connector left front and Pot in a electric box on top of box #1.
