Pin 2 from the ignition goes to the fuse box, doesn't it? Supplying power to a bank of fuses? Or am I reading that backwards?

F3 runs F11,F12,F13,F14, and F15, running a wide range of things, like the immobilizer, Steering Angle Sensor, Anti-Theft, etc

Pin 2 and 9 both go to the fusebox.
Pin 2 goes to pin 5 on connector X10459
Pin 9 goes to pin 10 on connector X10459
I'm not sure about F3

I'd like to find out a diagram or pinout for X10459..

This is what I have, assuming it's the same on your car.

It's not a pinout, but rather just pulling some info off what I can see on some diagrams I have that I used to troubleshoot a specific problem.

Pin 5 on X10459 goes to :

Horn Relay behind glove box, F9, F7, F8, F36, F37, F39, F41, F42, F44, and F45.


Pin 10 on X10459 goes to :

F1, F5, F2, F3, F6, F31, F32, F33, F34


Pin 1 on X10459

Wiper Relay


Pin 4 on X10459

Ground under passenger seat

That's the only places it's showing that connector on what I have. I know it's probably not all of the pins, but maybe that helps.

Thanks for the info!
I remember when I installed remote on e39, purple wire on ignition switch was for accessories and green for ignition.
Although I had 3 green wires on e39, and only have one on e53
