Elog cheat discovery

The hack job I did on trying to get the harness out of the truck left me with some bare wires hanging out the back of the sleeper. I drove it on our first salty road day and my message light came on the dash. I knew it was a Qualcomm harness issue but it ended up killing the communication between my ecm and dash to the point I had no oil, temp, volt, tac, and speedo.

On the way back to the shop I noticed something......my elog was on duty but not driving. As I was driving I put it into off duty and left it there. Yes.....I was moving 60mph down the road and the elog wasnt recording drive time. The 411 here is this wont help you drive from Chicago to Indianapolis because your gps will give location and I'm sure if you get checked they wont believe you had Scotty beam you over but it will help in a situation where you are parked and for some reason have to move the truck over 5mph to a better place a few miles down the road. I believe if you interrupt the speed sensor and cause the speedo not to register speed you can get away with this. I plan to try it since the elog doesnt record truck movement off the gps.

Not intending to hijack the thread, you can pm me if you'd like. Do you mind me asking what kind of make/model truck this is? I'm chasing an issue on a t660 that is losing all gauges and gauge backlighting as well as the green message center ~10 minutes after startup. As soon as the gauges go dead, the four ways and headlights turn on. Maybe a cecu issue but this truck had a Qualcomm and the harness remains just like in your pic of the bag of you cab. Inside harness I just stuffed behind the dash when I bought the truck.
