Having some electrical trouble hoping someone who has done this before can help. I have a 1998 v6 Mustang. Completed the 5.0 swap with my 1995 Gt that was wrecked. Everything is connected back up. Changed computer passenger side floorboard, electrical harness that runs through firewall up to front passenger side, ccrm from the overflow bottle. (There is a 4 wire connector on the car side that had a plug with 1 wire on the v6 harness that ran to computer - it does not connect with 5.0 harness). Remote keyless entry (locks, trunk, panic) all work fine. Headlights work. (No radio and I have finish connecting A/C controls to see if they work.
When I turn the key on dash lights up but it will not try to start. (No power to starter)
If I jump the starter (by powering connector near battery) it still does not start - but turns over
The "Theft" Light flashes fast on the dash
The power windows do not work.
Fuel pump does not come on
KEOE Code of 543 - failure battery to control module
Did I miss something? I think it may be something to do with changing the computer and that causing problems with the Anti-Theft system. Cant seem to find a method to reset or bypass. Not sure what a dealer would say if I took it to the stealership.

I did take notes and should have taken pictures so I can write up a detail of what this swap takes to complete. It was very simple have both vehicles. Most of the work was completed in a weekend with me and a buddy.
Did not swap out the dash yet. My understanding is that the dash will work except the Tach. The 98 has OBD-2 under dash and it has no connection according to my scanner. I have the 1995 OBD-1 under hood and it is where I got the KEOE Code of 543 - failure battery to control module
I am getting the name of a guy that can come out with a tuner and disable the PATS.
Well I switched the under hood harness that runs down the drivers side including the underhood fuse box. Car will run but not actuating the starter with the ignition. Since I was changing the interior with the GT anyway I have decided to change the entire interior, dash, and the rest of the wiring harnesses.
Looking forward to driving the new beast. Should be painted and completed in about another 2 weeks. Looking at a turbo kit from Craigslist gonna be fun.
