2021 audio Upgrade, Thoughts?

sweet buzz me when you are close by

 

Yoda, im local. did you get your 2021 stuff working? i need to confirm that harness worksk too!

 

got the harness from eBay

 

4awg diy fuse box, room for second line

stereo under seat velcroed, this is with seat all the way fwd...in driving position 100% concealed. grounded to seat post bolt which is totally solid. tested with multimeter all over truck.

i ran everything in floor and did a conduit with quick connectors so everything can be swapped now without taking anything apart. You could also go under carpet and come out where floor vent under seat is located.

 

The harness works I’m using it no problems 2020 sr5 non jbl

 

where on the firewall did your 4awg to thru the firewall with room to spare for another? Picture, please

 

right where all the factory wiring comes thru lower right when looking under hood. lots of space. I punched a hole with some scissors being careful to avoid any existing wires. The grommet there is like 3” diameter plenty of space could easily run a few more 4awg. It comes out right around your left foot kick panel conveniently easy shot to fuse box and or head unit. Literally easiest part of install. Pic tomorrow.

 

bump. I have a 2021 with damn power seats
thinking of starting a 2021 string since all the harnesses changed on speakers and HU
