I admit in advance that I assemble these kits by carefully following instructions and couldn't do it without the pictures. I am very ignorant of how most of it really works. Trying to install new upgrade BH-5 and BH-7 transformers.
BH-5: On the "IN" side does the black wire go to terminal labeled "plate" or "ground"? I assume the red wire then goes to the remaining one.
BH-7: Has 2 terminals, 1 marked with a black dot. Does black wire go to "dot" terminal or other one? Same assumption as above regarding red wire.
Thanks
