Hi all. I'm new to the site. Just bought a 2013 Bayswater last week and have already did a bit of mods - LED headlight, parking light, tail and interior lights. 300ok led fog lights. I also got the bimmercode with a bluetooth adapter and have modded DRL's removed LED errors, unlocking of doors, closing of windows with the remote. It was really fun with some trial and errors. My next project is alarm. I bought a cheap pke alarm just to have one.

I did a lot research and could not find a definite FRM wiring diagram but have found a few variations. My questions are:
1. How do you wire the central lock? FRM pins have one for driver lock, unlock and passenger lock. I can't find the passenger unlock.
2. For lights, since there are multiple circuits for left and right lights, can I tap into the steering wheel stalk to get parking lights? What is the wire color?
3. I wanted to use the heartbeat in the tach. I tried the DWA_Verbaut in SPEG but it still didn't light up. Some threads said I have to do it in Kombi too but DWA is not in my Kombi.

Any help appreciated. Thank you.
