Yes, If you can disconnect the black/yellow and black/orange, the motor's spark should not be affected by SLOW, shift interrupt or the ign key.
Fuel restriction wiring looks to be tan/orange and black. I expect the fuel restriction sensor (vacuum switch)to be near the fuel bracket, on the front of the motor.
