my paper hand written pages are getting trashed so I need to keep somewhere, I also hope when someone searches this is easily found. I want to do the amp and display screen outs also.
I never found all this info in one place when I started looking a while ago so This should help someone that wants to mess with stuff that doesn't want to buy the books.
There isn't really a need to have a stereo talk here, there are plenty of threads to do that. If there are errors, post it up.
pioneer cassette toyota #86120-60601 to 86120-60603 pin outs.
86120-60602 to 86120-60603 are 2004 -2007 LCs, N.A.
The 86120-60600 and 861-60601 are claimed on websites as 2002-2004 LCs, N.A. But I can't really confirm that.
All of them have three connectors at the back of the unit, they are labeled as R36A, R37B and R38C in the wiring book and fsm.
Starting with the small one, R37B, 12 pin, part# 90980-12183, back of radio, right side up, leftmost connector on the pioneer stock deck.
#1- open.
#2- red wire, CDR+ (audio right)
#3- white wire, CDR-
#4- black wire, CDL+ (audio left)
#5- white wire, CDL-
#6- white wire, MUTE to rear seat audio (RSA)
#7 & #8 open.
#9- pink wire, TXM+ (transmission to rear seat audio)
#10- blue wire, TXM- (transmission to rear seat audio)
#11-12 - open.
The R37B 12 pin basically connects the dvd audio, it also picks up an SGND bare wire to the DVD player along the way- and the data transmission lines to the rear seat audio with a mute interrupt.
Unplugging this will render the rear seat audio and dvd audio useless, but no critical systems will be affected as long as the other two stereo connectors plugged in.
Next in line is the smaller of the 20 pin plugs, R38C, middle plug on the pioneer stock deck.
Part# 90980-12259
#1-#5 open.
#6- brown wire, SWGND (steering wheel ground)
#7- white with red stripe, STSM1 (steering wheel controls left)
#8- black with red stripe, STSM2 (steering wheel controls right)
#9- pink wire, TX+ (transmission line to MFD or display)
#10- blue wire, TX- (transmission line to MDF or display)
#11- #13 open
#14- bare wire, SGRND (RSA)
#15- red wire, RSA R+
#16- white wire, RSA R-
#17- black wire, RSA L+
#18- green wire, RSA L-
#19- orange wire RMUTE
#20- white with blue stripe, ADIM (to body ECU- Dimmer)
The important ones here are the steering wheel control lines, 3, and the TX lines, pink and blue, the rest are rear seat audio. Plus dimmer.
#9&10, pink and blue is where you would plug in a resistor to take out the deck, there is no polarity for a resistor. To restore the wheel buttons for a new deck an aftermarket steering wheel control box from pac or axxess needs the three wires, #6-8. Unplugging this connector is what makes the HVAC not work. The resistor restores the communication to the MFD.
Next and last is the R36A, 20 pin, rightmost plug, part # 90980-12038
#1- blue with yellow stripe, +B (battery +12v line to stock deck, fused at radio 10A)
#2- open.
#3- Black with red stripe, AMP+ (amp signal wire)
#4- #6 open.
#7- orange wire, MUTE (to amp)
#8- yellow wire FR (front right speaker+)
#9- pink wire FL (front left speaker+)
#10- open.
#11- grey wire, ACC (key +12v power to stock deck, fused at ACC 7.5A)
#13- back with red stripe, ANT, antenna signal to antenna relay.
#14- #15 open.
#16- black wire, SGRND (to amp, speakers sground)
#17- green wire, BEEP,
#18- red wire, RR, (rear right speaker+)
#19- white wire, RL (rear left speaker+)
#20 open.
