Installed '14 clock in '15 ... Keeps resetting

So I installed a 2014 clock in my 2015. I followed the instructions that I saw on here ... Tapping into the wires in the head unit. But everytime I start the truck up, the clock doesn't keep time and defaults to 1:00. Is there anything I missed?

 

Sounds like the clock does not have constant power, and likely only has accessory power. Did you double check?

 

Problem solved. Turns out the positap I was using didn't pierce the constant power. I switched to a smaller positap and it works now. Thanks!

 

Yeah, but its still a year off.

 

Glad you figured out the problem, having a normal clock in there is much nicer!
