I need help retrofitting bmw e38 hydraulic trunk boot

[orozcomtz]

Hi,

I'm currently in the process of retrofitting the BMW E38 Hydraulic trunk boot. On the 15 pin HKM connector I cannot figure out where PIN 12 goes to. I looked at the WSD and It says that it goes to pin number 2 on a 3 pin yellow connector for the trunk lid locking switch but the connector is simply not there. Any help will be greatly appreciated. Thanks

Look on Utube - Edwin did a video on this several years ago.

Sorry to hijack but it's still relevant. Where is the best place exactly to mount the tilt sensor on the underside of the trunk lid?
