turbo timer not working

I have a Blitz Voiced Guided Turbo Timer which has the main harness running through the ignition and another harness for the hand brake and speed sensor (which I did not hook up). The first time I installed it, it ran perfect. Since then I tried to clean up the look by tucking the harness away. I unplugged it when I did that and after I finished plugged it back in and it doesn’t work. I can turn on the timer in ignition but when I shut the ignition off the timer shuts off as well. I checked and re-checked the harness connection and it’s connected properly, but I still can’t seem to find the problem.
anyone know what the problem could be?
Thanks

sounds like your 12volt continus power wire what did you wire that to and does whateever you wired that to work still? maybe check fuses see if any are burned out.

I bought a timer harness so installation was a snap. Where should I check for the blown fuses?

Im guessing then, that you dont know where the harness takes its power from?

The wire for the hand brake is not connected? In that case there is your problem.
