Firewall Access?
Anyone have any success finding firewall access from the engine compartment to the passenger compartment?
Want to plan out how to route cables for a STI-R or 9500ic or Laser Interceptor. Thanks! |

I need the answer too. Gonna install a 9500ic soon and don't want to pay ridiculous installation costs for an easy job.

if you take the cover for the positive terminal off it'll expose the fuse box area, if you look at the bottom left corner theres a couple of rubber sealed holes.
Cut a littl eslit in one and you can push a wire through and it'll come out behind the passenger glove box |

How do you get the wires OUT of the fusebox?
Quote:
I wonder if the F30 3 series has the same unused rubber nipple under the steering column area/wires as the E90 did. That made wire runs very, very easy. Cut a small slit and pass through as needed. |

I'm going to look for this later. Hoping I can route the JB4 cable through it like I could on the E92

Looks interesting- but what happened to under the steering wheel access?
Quote:
Never would have thought it possible to route as you did. I wonder if such will work on US based cars. Thanks! I'm still a but confused (my F30 335xi is on order), but will check when it eventually shows up. On the E90 ther was a rubber like "nipple" under the steering wheel by the main harness entry. Made life easy. I wonder if the F30 has such as well. |

I wrote a DIY for the retrofit of a DEFA WarmUp interior heater (Termini 2100).
It's in German, but well illustrated. I used a pull-wire to route the cable through the firewall. |

Helpful & well written, but I have a question
Quote:
Does the entire glove compartment need to come out to run the wire? Or, was this needed to install your heater? Thanks! |

Then pull the wire together with the cable into the engine compartment. In my case it is a cable of approx. 15mm diameter. So, the removal of the glovebox was helpful. |

Even though your write up was in German I used a translator, which helped quite a bit. |

This grommet worked!!
Just got a 2014 335xi & followed this thread for firewall access:
http://www.f30post.com/forums/showth...light=firewall My 335 does NOT look the same- I have a rain funnel or the like not shown in these pics. However, I can confirm that the rightmost grommet (has a smaller arrow and closest to the fusebox) in the pic did work, although I needed a stiff and narrow fish tape. I used a heavy duty 3' long cable tie, which was initially too wide so I carefully cut it in half with a utility knife. NOTE: The pic below is from the link above. It is NOT my car. Better still, there is a switched 12v power source on the lower dash cover I removed. Its the plug under the passenger footwell. I'll finish the Laser Interceptor another day. Looks like rain is heading my way. Last edited by jws360; 12-21-2013 at 03:17 PM.. |
