I've got a new 1U2Z-12A199-AA in my truck right now. It starts with a 1/2 second ignition key engagement, and matches the performance of the Original module.

My, 1U2Z-12A199-AA, has a Modern Ford/Motorcraft sticker on it, it is lighter and has cooling fins at the back. Doesn't really match the original in looks very much. It came in a Ford/Motorcraft Box.

One thing to be aware of, there is a problem with the wiring colors of Replacement Motorcraft and Aftermarket replacement DS-II modules. The colors invert themselves at the DS-II connector.

Wire Color for original Factory wiring and Original Factory modules:

START CIRCUT: Red/Blue stripe. (Matches starter solenoid wire.)
RUN CIRCUT: White/Blue Stripe.

Wire Colors for Replacement Motorcraft and aftermarket modules

START CIRCUT: White
RUN CIRCUT: RED

Picture of Module... Ignore The MCU (Microcomputer Control Unit) above the ignition module.
