Audio Wiring Questions 2008 Yaris RS 2dr. HB
Hi, I am replacing my factory 6 disc CD player with a Kenwood eXeclon DPX792BH.
My favorite Toyota dealer printed out the factory Audio System Wiring Schematic for me. Most of the wires are easy peasy. However i'm unsure on a few wires. 1) The [blue] Toyota wire in Pin 4 is the constant power from the battery or (BAT), however i am a little worried. This wire is actually just a connection to the 15a dome light. If someone left the dome light on, would power not be also on to my head unit? or would the ACC [grey] Toyota wire Pin 3 switch the unit off automatically as soon as the car is turned off? 2) The 2 Toyota green (ILL+ and ILL-) wires have no connection point per the Kenwood wiring diagram. Am I to terminate these wires and leave them in the dash? My assumption is these wires allow the Toyota dash light fader to dim the head unit. I'd like this to work, but if its not something kenwood can do, then i guess i'll just leave them. 3) the Toyota Pin 3 [white] SPD wire has no where to connect to the kenwood unit. It must be essential... or not? 4) Kenwood provides 3 addition wires. a) [Brown] mute control for navigation. (do not need) b) [Blue/White] Power Antenna or power amplifier power control. (which i will wire to my amplifier for remote turn on.) c) [light blue/yellow] For steering remote wires I am left with a group of 4 wires from Toyota also. Pin 15 [red] ARO Pin 16 [black] ASGN Pin 17 [white] ALO Pin 18 [grey] AGND Pin 19 [red] AUXO My assumption is that these are pre-wired in for factory steering wheel controls. Since the Kenwood unit can have and Iphone or Android attached by plug or just by Bluetooth, I imagine that it will mute the speakers itself when a call comes in, thus leaving the brown Kenwood wire useless (as i do not have sat.nav.), correct? I haven't looked at after market controls yet but that's where Kenwood's [Yellow] wire will go to. correct? i find it hard to believe with all the options on this head unit that one wire will control all. That's my small little question post... please let me know if there is insight into the questions i have above, and I appreciate your time, Cheers Rob. |
