My z120bt turns off when starting the truck from acc. I have seen a few threads thy people use a different 12v ignition wire. I was thinking about it. I think that if u put a relay on your 12v ignition wire and use 12v as your source. Twouldnt that keep the ignition power from cutting out. I would think the relay would still stay on troth voltage drop. Any input would be great. Thanks
