The "crank-pallet" is what I started with. But integrating the factory wiring with the BDR chassis is very complicated. I had to hire a professional to do that for me, as I am not an electrical engineer. Keep in mind, my car has a 6R80 transmission. There were no parts available from Ford for this swap when I built it.

The "instruction manual" supplied by BDR is really no help at all. It basically says, 1. Install engine 2. connect wiring harness. There is absolutely no information for installing the Coyote engine.

I used the mini 80A alternator. I have an Edelblock blower installed, and that requires a change in the front belt set up. 80A is plenty. With all the lights on and the engine at a fast idle, the alternator makes 28A. Electric PS requires a 30A circuit.

I haven't decided on the e-PS. It can be done by installing the motor and controls under the dash. You'll have to do some cutting and welding to do it right, which to me is not a big problem

I'm really looking at Unisteer, as I see a lot of advantages:
- the motor and column are all one piece.
- You can add a center horn button
- move blinker arm to the left side
- tilt column
- removable steering wheel.

When I get ready to do this, I'll contact them about specific measurements and see what fits. Or maybe they can make me a custom column.

My car came with an aluminum gas tank. It is a special order item. The hole is specifically cut and drilled for a specific fuel pump. This is the one I am using; supplies plenty of fuel for 600+hp. It fits the pre-drilled hole perfectly. https://www.summitracing.com/parts/tnk-gpa-4


I spent a bunch of time altering the bucket that came with the fuel pump so it would fit around the internal baffles. It retrospect it would have been a whole lot easier and better to simply install a Holley Hydro-Mat, and throw the bucket in the trash.


Speaking of fuel tanks, mine was full of aluminum chips and shavings. Make sure you remove the tank from the chassis and clean it out really well.
