DIY - BMW Z3 Keyless Entry Wiring Easy + Hazards (E36 also)

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 http://www.unofficialbmw.com/images/z... 2. Locate ZKE4 module https://www.bmwgm5.com/Images/GM4/GM4... 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.
