Battery cable squib resistance
#30
Battery Safety Terminal BST is another name for the squib. I have searched all over and was about to give up until I found this thread. I wanted to post the BST so it would be easier for people to find.
I have a 2006 S that I am doing this fix to as soon as I get a resistor from Amazon delivered.

Thank you for the answer, but "the piece plugs into box #19" , where I can find it? Somewhere I think I read that the bmw E39 repair kit for the BST might be good for our Minis, could I look for that? Or alternatively what should I do in your opinion?

To clarify for myself, the battery squib is to be completely removed from the positive terminal off the battery cable end? Once the resistor is in place how does the system receive its power to activate? I guess I am unfamiliar as to what exactly this wire harness does and how it works...

Forgive me if I seem unclear...
To answer your question
No - the BST (squb) should stay in place connected to the positive battery terminal as is. Yes you can undo the main positive cable if it makes it easier to access / perform the fix.
Just trace the small black lead that has a connector that plugs into the BST. Within that lead there are two small (or one? - I don't remember) wires sheathed within that lead.
Simply connect each end of your 3.5ohm resister to each ends of those wires as shown in post #19. to complete the circuit. Be sure to plug that wire back into the BST after your done if you removed it to solder the resistor.
Here is another link with pictures that might help if you haven't see it.
Hope this helps.

It's been a couple of years since I performed this fix.

I did the squib modification and reset my light my creator c310+. Everything seemed OK but my battery died overnight. I also set my interior light so it would come on with the door, so hopefully that did it. Here's a closeup of my repair
I thought it would also work to use the end the positive battery cable and disconnect the squib line from a junked car. It looks like I could crimp it to the end of my battery cable. Maybe with something like this. https://www.zoro.com/grote-battery-splice-2-awg-tin-pk10-84-9553/i/G1295813/?recommended=true
Does anyone know what guage wire this would be?
