I have 95 sc300 i want to install navigation. I had searched the board and internet so looks like there is speed sensor no 1 that I need tap into ist that right. Looks like it is green wire in the middle connector for ecu 3. is this right. Where I can find reverse wire? Is ecu pinout same for all sc300.

 

here's the reverse wire, it's easy to get to while installing the navigation unit.



it's right under the shifter

 

so that red wire for reverse. Can someone confirm location of vss
