5.2 5.9 magnum EFI plug and play harnesses

i have an off the wall ? i just picked up a 1978 RV (25' kings highway w/35k miles and looks 5 years old) with a dodge industrial chassis and a 440. I have been away form mopars for about 20 years (even though i have had a 70 340 duster that sits...) i dont recall an efi bbm. It would be nice if i could convert this one tho... really just thinking out load here and looking for ideas, not trying to jack your thread but i feel i may be lol

Oddly enough, seeing your username here, i have been playing with fox mustangs myself most of that time (tho 4th gen fbodies seem to be an infection right now). i have at least 6 4 eyed foxes :)
