Wolfer,
Rookie2 had sent me the wiring diagrams of the radio and the amp for a LX450. Shown below is my attempt in laying out for you the pins in various connectors.
There are two connectors at the back of the oem radio. One connects the CD changer and the other, "R1" connects the radio to the amp. This white 15 pin connector, "R1" (female) has the pins laid out as follows:
1^^2^^3^^4^^^^^^^^^5^^6^^7
8^^9^^^^10^11^12^13^^^14^15
1 = amp turn on; blue
2 = ILL +
3 = ACC; blue/red
4 = Bat +; blue/white
5 = Mute; white
6 = FL; green
7 = FR; blue
8 = ANT turn on
9 = ILL (variable controlled by the dimmer)
10 = Telephone mute; red/green
11 = Power ground; Violet
12 = Signal ground; brown
13 = Beep; black
14 = RL; yellow
15 = RR; red
There are 3 connectors to the oem amp. The one that corresponds to "R1" is called "S16" at the amp. This white 15 pin connector "S16" connects the radio to the amp. The pin configuration in the female connector is:
1^^X^^3^^4^^^^^^^^^5^^6^^7
X^^X^^^^^X^11^12^13^^^14^15
1 = amp turn on; blue
2 = blank
3 = ACC; blue/red
4 = Bat +; blue/white
5 = Mute; white
6 = FL; green
7 = FR; blue
8 = blank
9 = blank
10 = blank
11 = Power ground; Violet
12 = Signal ground; brown
13 = Beep; black
14 = RL; yellow
15 = RR; red
Another one is a 10 hole (7 pin), gray connector which supplies power to the amp and connects the front speakers. The pins in the female are:
1^^2^^^^^^^^3^^4
5^^6^^7^^X^^X^^X
1 = FR speaker +; light green
2 = FL speaker +; pink
3 = ACC; gray
4 = Bat +; blue/yellow
5 = FR speaker -; blue
6 = FL speaker -; violet
7 = Ground; brown
The third connector, "S17" is gray and has 6 pins for the rear and subwoofer connections. The pins layout in the female connector is:
1^^^^^^^^3
3^^4^^5^^6
1 = RR speaker +; red
2 = RL speaker +; black
3 = RR speaker -; white
4 = woofer +; light gray/black
5 = woofer -; light green/red
6 = RL speaker -; yellow
Please double check the pins and wire colors for your truck before install. Keep us updated with your project.
