New hall-throttle position switch by Shoebox Electronix. A version of this kit will fit throttle bodies with a single switch. If you have a throttle body with dual switches this kit will not work for you and at this time we do have a solution for you. The hall switch provides idle and full throttle signals to your ECU electronically, as opposed to finicky vacuum systems, or mechanical microswitches. Your old grey cam is replaced with a magnet disc, containing two 4.8 gauss Neodymium magnets, which activate a hall sensor at the two throttle shaft endpoints. All components are pre-mounted on a double-sided printed circuit board, which is tested individually with the Magnet Disc supplied with your kit. Simply remove your old microswitch, replace it with the circuit board assembly, and make two simple connections to 12V and ground with wires & connectors provided, reconnect the two wires from your old switch, and your installation is complete. We have even provided an LED indicator to make adjusting your new switch easier. The circuit is protected against overload with a resettable fuse and isolated from your vehicles 12V system via a 5V regulator chip. All required parts, along with a detailed installation manual is included. The throttle switch assembly will be covered by our No Hassle TYTM Shoebox Warranty for 3 years. As an added bonus, we are also including a FREE 3mm Hex Wrench for adjusting your new TPS.
