6.4 engine controller options

so im at the point of my build where i need to get a controller.... its the last major part i need....
Its a 70 duster 6.4 hemi, 274cam, tti headers,x pipe 3" magnaflows to the bumper, full return fuel system threw fuel rails (stock injectors).... magnum t56

So im gunna get everything dyno tuned once its ready to fire up, but what engine controller to get???

I have had my eyes on modern mopar extreme 6.4 engine controller... but i called, it only runs a signal wire for fuel pump.... i have to run my own switch for radiator fans, and run a voltage regulator for alt.... and it appers to be a 03-05 ecu from pix, so that means it has to have a custom harness....
Its 2700$

Other one ive had my eye on, and looks better and better, is the mopar performance 392 engine controller...from what ive read, this one runs signal wires for fuel pump, radiator fans, and controlls alt... ecu is 2016 style, and harness is all factory mopar....
Its 1800$....

Whats your guys imput??
Thanx
