Review on Metra 70 2057 2014 Bypass Harness by Fred Massingill

Revainrating 5 out of 5

Perfect for Car and Car Electronics

Works great on my 2018 Sierra with non-Bose system. The only reason it has 4 starts is because it is 20 gauge wiring and the mating connector adapter is 18 gauge for speaker wire and the power is 16 gauge.

Pros
  • Car and Car Electronics
Cons
  • Operating Speed
