sorry for the delay............

Greetings...... “Hi, I’m Don (akaCustomer and I look forward to helping you!”

You should use a Wiring Adapter like METRA or Scoshe, as that would be color for color & fool proof
Depending on "which" Factory Unit you have, this is for "Base" Units, this is "hard wire" colors
Constant + 12V = blue/yellow
GROUND = brown
Ignition / Accessory + = gray
ILLUMINATE = green
POWER ANTENNA = white/blue
LF SPEAKER = pink +
LF SPEAKER = - purple
RF SPEAKER = lt. green +
RF SPEAKER = - blue
LR SPEAKER = black +
LR SPEAKER = - yellow
RR SPEAKER = red +
RR SPEAKER = - white

hello?

Customer: replied 4 months ago.
the radio im installing is jensen vx7020 dbl din. the color codes you listed...are they for harness coming out of sequoia or from aux toyota harness that plugs into car harness and then wires to jensen harness?
Expert:  Don 'Mo Lurch' replied 4 months ago.

that is the Toyota Factory wires
You should have the Jensen wiring diagram to match the Positive + & Negative - colors

???

.

Please reread my answer..........
Toyota Harness wires
RED = Right Rear Speaker (+)
BLUE = Right Front Speaker (-)
GREEN = Dimmer on Jensen Radio
Not sure if you have installed before, but would you like me to "match the Jensen wires with the Toyota wires........
This is not that difficult & that is also why a Wiring Harness Adapter is recommended

let me know
