Hey guys, tried looking all over for an answer but I keep hearing all different things. So i've decided to come here and seek help.
I have my whole system installed besides the LOC because I am confused on the wires..

I am not sure what wires im supposed to be tapping into..
I have the stock head unit (Pioneer T1808 )
There are four connectors, Two in the middle, one far upper left and one lower left (if looking at back on unit). I'm not sure which harness has the LR + - and RR + - to tap into with the LOC.
Any help will be appreciated!

Also I have my remote wire tapped into my cigarette lighter positive. (Only works while key is to on position)
Is that okay/safe?

 

bump thread
anyone?

 

Get this:

I dont *** with ebay.
Too many problems..
I know someone here has to know what wires/wireharness to use.

 

why buy that when i already have a loc that costed me 25 bills and my wiring kit has a remote

 

Take a look at the electrical wiring manuals here....

Check out the audio section for the wire colors you need to tap into.

 

is the 2007 wiring diagram the same for 2010?

 

I would say yes for the audio....I can't imagine that the colors of the speaker wires would change....especially from model year to model year.

I just checked the 05 vs 07 and the colors are the same.

 

I guess cig lighter will work as a remote wire. Remote isn't gonna draw much. Never used that before but as long as its switched power source your good. If you pop a fuse you know it's not gonna work. Then I'd look for the switched power on the radio.

One of those plugs is steering wheel controls

I found a diagram for 2010
Lr + black
Lr - yellow
Rr + red
Rr - white

Just googled "2010 scion TC radio wiring diagram" and there is a link for 2009 and it lists 2010 on there

For what it's worth some of the wiring colors are listed differently for 2009 and 2010 so it looks like diff years may have diff wiring diagrams

i wish they would just have a official wiring diagram so i know legit which wires to tap into.

 

Buy this:

and this:

wire both together. use green/green black and purple/purple black as well as blue (or blue/white) as your remote.

Easily accomplished, and you're not hacking your factory wiring.

 

^^ Same as the ebay one. Good find.

 

got it to work, thanks for all your guys help
