I have error code -04 on display  
First how do I bypass the E-brake switch it has three wires yellow/green, green/white and green  
Second I need to check voltage on a bunch of different places but where should I place com lead to get correct reading.  
The only noise i get is when the car is switched in to reverse not sure if this indicates anything

Third what should the voltage be on each side of the disconnect

-04 is a normal reading. The parking brake interlock switch will sometimes need adjustment. One of the screw holes is elongated to allow for adjustment. Be careful to prevent accidental runaway when testing the switch.
