New Head Unit Install

Hello

I'm just trying to help out a friend and im sorry this question has been asked before but I just don't see a clear enough answer for me and any help is much appreciated.

The truck in question is a 2014 tundra double cab with non-JBL but with factory amp.

After installing his radio there is not sound from the doors which I know is from the amp but can i simply just connect the blue remote amp wire? or is it just the wrong harness and he needs the harness that uses the "iDatalink Maestro RR Interface Module"

He is the one that ordered the harness so im assuming he just got the wrong one not knowing he had a amp.

thank you for any help

 

What head unit was installed and what harness was installed? There should be quite a few components to install an aftermarket radio. Maestro unit, Maestro harness, USB adapter cable, satellite antenna adapters, FM antenna adapter, etc.

 

The wiring on that non-JBL factory amp is wild. This video helped me out a ton. Oh, and listen to @Tundra234 - he knows what he’s saying!

Its a pioneer head unit and the harness he got was Crux SWRTY-61N Wiring Interface

 

Right - that vid should help you understand the factory amp wiring, though and why he bypasses it.
