Hi Craig, Unless you've disconnected the 2.1L Dynamic oil pressure warning system. The 0.9B switch is needed. It's a ground below 0.9B and an open above it. Without the correct signals the buzzer sounds. If you want access to the oil pressure circuit, go the 0.3B pressure switch on the left side of the 2.1L motor, near the push rods. Install a 1/8" pipe thread Tee using the 0.3B drilling, the 0.3B switch and the new temp sender. It may be necessary to modify the push rod tube splash shield. Home Depot has a full assortment of 1/8" copper pipe thread fittings. Use Teflon sealing tape on threads. Regards, John |
