I have HONEYWELL SECONDARY HI-LIMIT L6006C installed as shown in the following illustration (note 7).

Does anyone know how to wire Mcdonnell & Miller RB-24E?
this unit comes with 4 wire, two yellows, a white and a red wire.

    PK/BL and BR/Y is the 24v secondary side of the transformer. You'll have to see which is 24v and which is Common. It looks like BR/Y is 24v but double check. 
    On the GuardDog,
    Red is 24v. White is Common. Splice those to 24v and Common at the transformer. The yellows you can connect in series right before the L6006.
    M&M also offer wiring harnesses to make it easier.
