THROTTLE POSITION
ACTIVATION SWITCH
PN 15961
The NX TPAS is more durable and contains short circuit protection that other, similar products, do not.
The TPAS is designed to work with most domestic and import EFI vehicles. The 15961 is designed to trigger a
relay, 1⁄2 amp maximum current draw, at or near wide open throttle and is adjustable to work with most vehicles
having a 4.0 volt signal at wide open throttle.
1. Unlike other currently available units the NX TPAS may be installed under the hood. Mount the unit in a
place so access the small adjustment screw is convenient. Make sure the unit is located away from any
heat source, i.e. exhaust manifold, header, or EGR. This unit is for use with 4.0 volt or higher at Wide Open
Throttle.
2. Following the wiring diagram, route all wires but make no connections.
3. You must determine which wire on your vehicle’s TPS is the output signal to the vehicles computer. Refer
to your vehicle’s service manual to determine which is the output wire. Connect all the wires as shown in
the diagram.
4. Calibrating and testing your TPAS: After all wires are connected as in diagram A, have an assistant open
the throttle to maximum and hold it. If the LED is “ON”, using a small blade screwdriver, turn the adjustment screw clockwise until the LED goes out, now rotate the screw one full turn in the opposite direction
(counterclockwise), the switch is now ready for use. If it is “OFF” rotate the screw counterclockwise until
the LED comes “ON”. Close the throttle, the LED should go out, now apply wide-open throttle, the LED
should come on at or just before full throttle. If it does not repeat step 4.
