Review on Enhanced GM Data Retention Harness - Metra 70-2003T by Tim Kallimanis

Revainrating 4 out of 5

Perfect for my 2004 Impala

Perfect for my 2004 Impala. This allowed me to fit a factory radio in the trunk so I could use it for doorbell, key fob programming, etc. Please note that you need a Metra SP-2003 or other type of speaker for the doorbell.

Pros
  • Power Supplies
Cons
  • Annoying
