BE ON NOTICE, the one I linked is for the SLK230. Do not freak out, the only difference is that one fuse is 20 amp in ours and all are 15 amp in the '230. Just transplant that one yellow fuse are you are good.
Im running that exact one right now, I have my DJ-fixed spare in the trunk.


And REMEMBER, it is fine to drive the car without a spare tire. It is nuts to drive the car without a KNOWN GOOD spare RCM !
