How Many BN2 Overdrive Relays??

Finally getting to the final stages on my 100M so starting to tackle the mish-mash that is my wiring. Many splices and non standard connections that need correcting and I have not gotten to the point where I want to replace the whole harness. One quandary - The wiring diagram for the BN2 shows two overdrive relays. There is only one on my car and the overdrive worked before I started repairs. It is not original so I purchased the correct part but do not see any sign or pictures in restoration guides where the second one should be located. Electricals are not my forte so may be missing something simple.
 
BN1/early 100's/3 speed box had a two relay system with a centrifugal switch. The BN2's/4 speed box had only the one relay and no centrifugal switch. Find the wiring diagrams and all will be revealed.
 
thanks. The laminated wiring diagram I ordered is labeled as a BN2!! Looks like I got screwed. Found the BN2 diagram in an old shop manual.
