Just got a deal on a MSD 6ALN
Used for three races

I wanted to install it in a 5.0 Mustang

I mounted the unit, used supplied harness, the green and purple wire are not used on a Ford.

Heavy Red wire to positive battery, heavy black to ground.

Orange and Red wire to Coil, Black and Brown wire go into the coil connector that runs to the dizzy.

Polarity is correct on hook up of coil.

The instructions available for download from MSDN do not mention the brown wire in the installation. They reference a white wire. 6ALN's use a white wire for a kill switch. The race team I got the box from does not use the kill switch on the box.

After hooking everything up, it does not work.
I installed a 7k limiter in the box, the car may turn 7k ONCE but that's really not the issue.

I know the box is good, the team checked it after removal. the team races NASCAR.
It's July 4th and they are not in the shop.

HELP me please
