Even though Bob says it I also screwed up the 15 pin mini. To be very clear
Viewed from the chassis front. Male plugs pin 1 left side Female plugs pin 1 right side But that said the systems running fine now by simply doing the pin 2 and 3 approach. Next things. Battery backup to the GPS unit then RS422 and communications. My unit took a solid 2.5 hours to lock etc. But I was not on the good antenna. Instead an inside unit on the bench. Far from optimum. I just did not want to screw with the antenna connector and the L + 220 ohm R to fake out the GPS unit. Thanks for the help every one.
