I just bought a 2005 R52 S and would like to add gauges. I don't want to cut into the original loom. I want to use add-a-taps for connecting to a power source, a switched power source, and an interior light source. I would really appreciate if someone could tell me which fuse position to use? Is there a better way than add-a-taps? I am going to install and oil pressure and a boost gauge. As always, TIA for any help I can get.

 

Suggest you get a voltmeter...then open the fuse panel by the drivers side leg area ..
And just find which ones are hot, and which are switch, then use the add a fuse/fuse tap...the make sure it is on the unprotected side, add an inline fuse....and you can use any one that suits you needs...I suggest always using a switched on....and there are a few good bolts to use as grounds in the area if you look around.
Don't really have a specific fuse #, cause you will find mini's were EVOLUTIONARY in their production...with many changes rolled out based upon the production date, not model year...so the fuses changed several times for some items.

 

Use the Cig. Lighter fuse and you should be fine.
