How to easily install a keyless entry system to Z3 or E36 3 Series:
Read This for the exact pin numbers!
1. Remove glove box

2. Locate ZKE4 module

3. For powering up the keyless entry module use 2 pins from the black connector X13252
- Pin 10 - Power Supply - red/green/yellow
- Pin 15 - Ground - brown
3. For Lock/Unlock use 2 pins from the purple (or yellow) X13253 connector
- Pin 7 - Brown / Black
- Pin 17 - White / red /yellow
4. Lift up hazards switch and splice into 2 wires
- grey / red
- blue / brown
Shorting those two should start the hazards
5. Use a simple 4 pin relay:
- 85 - ground (from the module you are installing for ex)
- 86 - Hazards output from the module (+12v)
- 30 - grey / red from the hazards switch
- 87 - blue / brown from the hazards switch
Trim and isolate all wires you are not using, and put it all back neatly and you're done.
I advise testing each of the pins you are splicing into before connecting just to make sure you got the right ones.
