I'm in the process of putting a chevy engine in my cutlass. These wires are coming from under the heater box & I dont think I need any of them... Can i cut them
I know i need to keep these for my blower motor & AC so these will stay

The emissions harness is one piece that comes out through a fitting in the firewall below the heater box. Just disconnect the harness from the ECU inside the car, unbolt the fitting on the firewall (you may need to loosen the inner fender to get at it), and just pull the whole emissions harness out of the car. It is completely separate from the engine and light harnesses that route to the firewall connector under the brake booster. Cover the hole with a plate and you're done. Lots cleaner that way, and you're assured of only removing the wires in the emissions harness.
