The blk/crimson twine from the master cylinder brake transfer(es) need to first be disconnected. ?this wire may be located at the nine-terminal flasher #54 or on the chance turn on later busses which do not have the nine-terminal flasher. ?the new twine can then be spliced to the blk/crimson twine or linked right on the brake transfer terminal. ?the wiring looks as if this:. The sprint speedo indicator bulb used with the three-terminal flasher relay is attached from the ( ) supply to #49a and it flashes contrary to the flip indicator bulbs. ?as an example, when the flip indicator bulbs are lit, there may be 12v gift at #49a. Which means that both facets of the dash bulb have 12v on them and no contemporary can go with the flow thru the bulb. ?.
