TOTO THP3523 – Frequently Asked Questions
1) Is the TOTO THP3523 a sensor, or just the wiring?
Just the wiring. The THP3523 is an extension harness that connects to a TOTO sensor unit; it does not include the sensor, solenoid, or valve body. If your sensor has failed, you need the sensor assembly, not this harness.
2) Will the THP3523 harness work with any brand of sensor faucet?
No. The THP3523 is a TOTO service part and is intended for TOTO sensor units. Connector keying on sensor harnesses is brand specific, so match the harness to the TOTO sensor model you are servicing rather than trying to adapt it to another manufacturer's faucet or flush valve.
3) What is the TOTO THP3523 extension harness used for?
The THP3523 is a TOTO extension harness for sensor units, sold as a replacement part for sensor-operated washroom fixtures. It extends the wiring run between the sensor and the unit it controls rather than being a sensor itself. Order it by TOTO part number THP3523.
4) How many harnesses come in a bag of TOTO THP3523?
Each THP3523 bag contains three harness types, so you get the assortment in one pack rather than ordering each length or connector style separately. That matters for a maintenance tech carrying one part number for several sensor installs.
