How to wire front bumper to trunk? thru firewall?

[bimmerFanatic]

I'm installing a non-geniune BMW parking sensor system and would like to know the best way to wire the front bumper sensors to the main unit in the trunk? The genuine BMW sensors magically hookup to connectors next to the Xenon lights but with these, I have to wire up the whole car.

1. Sensor is in front bumper What is best wiring path through the engine block to the firewall?
2. How do I retrieve wire from inside? Do I have to remove console or glove compartment?
3. What is best path from inside to Wheel well in trunk?
4. I thinking of a synonym of firewall for my searches, is it Grommel?
5. Any other threads repeat this question?


thanks!
