Subaru Wiring technician expert help...

[Trap63]

First of all thanks!

Subaru BRZ has an inside accessory harness beside front panel, here you can wire accessories with proper harness, the IV

I wire the harness IV to twin foot (JDM blue and white alternate) and control module. I tried several times without success.

So I read very well wiring cable procedures and try with tester to see if voltage is there…(no voltage on pin 11 and 14)

Today I decide to see and tester the 15 pins harness on car …and I found the problem.
My car harness is populate only for the two lines of pins, there aren't pins from 10 to 15 and pin 11 (room lamp) and pin 14 (B KUP) are mandatory to properly operates.

I enclose photos of my harness on car where you can see loosing pins.

The questions is:
Where can I take the signal of these two loosing wire?

Thanks….

Finally!! Someone else sees this mystery harness. So have you figured out exactly what this goes to? Or even what you can use it for? Would love to see what we can do with this

maybe America was discovered more simply by Colombo rather than this harness!!!! now the trouble is that in Euro/USDM (LHD) are loosing pins from 10 to 15.

For twin foot dual (blue and white in accordance to light on or engine on) is mandatory wiring to pins 11 and 14.

Japanparts send me translate diagram (thanks....) to english (I already know them....as meaning), but I googled sometimes ago. Problem still live...no pins as you can see in my first picture...

Therefore some subaru technician is required. I think you can do a lot of things with HarnessIV




By the way their english is very broken (Ok I am not Shakespeare...but I speak since 1980....) and some definitions aren't common on english car diagram.
So BKUP might mean backup lamp? room lamp is the map light? or something else?
