You do not cut the black or the white wire. You leave the white wire alone altogether. Cut the Yellow wire and strip some insulation off of the black wire BUT LEAVE IT INTACT! Measure your resistance between the switch side of the yellow wire and black wire. Match up the resistance with the resistors you have just purchased and solder them together and to the black wire which is still intact with the system and the non switched side of the yellow wire.

Try to start your engine and that should be it.
