I have a 99 Z71 and I took my trinity off yesterday, put back to original back up and all that good stuff, and I took it in the house to update it. When I took it back out to plug it into my truck and tried to pick a tune it says Trinity was used to flash crom or something along the lines of that. I went to options and last tune written and it says Trinity is not married yet. So what do I need to do to install it back onto my truck? Any help would be appreciated.

Thanks,
Jason
