Genuine Mini Spares product, fits 3 and 4-synchro gearboxes except for rod change types which use
GAE191. This switch replaces the plug on the front of the remote-shift transmission case. It is triggered internally by the shift linkage when reverse is selected. This must be fitted with an insulating fibre washer and a small plug
22G351 in the gearbox to activate the switch---the original washer
2K7914 is no longer available but
1B3664 can be used although the internal hole is slightly to large.
BEWARE OF SWITCHE AVAILABLE WITH WRONG THREAD AND PLUNGER SIZE-ALL USING PART NUMBER GAE131 THAT ARE MEANT TO REPLACE THIS PART,BUT OURS IS CORRECT
