Reno A&E 802-4 11-Pin Loop Detector Wiring Harness
The Reno A&E 802-4 style 11-pin harness is the wiring interface between an 11-pin vehicle detector and the gate, barrier, parking, or access-control panel. Instead of landing detector wires directly on the detector body, the harness plugs into the detector and provides individual leads for detector power, loop input, relay common, normally open, and normally closed contacts. In service work, a harness is often replaced when the connector is loose, corroded, heat damaged, or when an old detector cabinet has been rewired several times. The harness is not a detector by itself; it must be paired with the correct 11-pin loop detector and connected to the correct voltage source and control input. It is commonly associated with Reno AX, AX2, AX2DL, B, BX, BXC, and BX-LP detector families, but the technician should always follow the detector pinout and operator wiring diagram.
Compatible With
- Reno A&E AX Series 11-pin detector installations when the pinout matches.
- Reno A&E AX2 and AX2DL detector families where an 11-pin harness is specified.
- Reno A&E Model B, BX, BXC, and BX-LP detector families using an 11-pin Amphenol-style connector.
- Gate operators, barrier operators, parking systems, and access-control panels that use an external 11-pin vehicle detector harness.
- Replacement of damaged, missing, brittle, cut, or miswired 11-pin detector harnesses in compatible cabinets.

Technician Note
Before replacing a detector, inspect the harness. Loose crimp contacts, wrong wire landings, or corrosion in the 11-pin connector can mimic detector failure.
Before Ordering Checklist
- Confirm the detector uses an 11-pin Amphenol-style connector.
- Verify the detector family is listed for an 802-4 style harness.
- Label the old harness wires before removal.
- Confirm power, loop, relay A, and relay B terminals before energizing the system.
- Replace damaged wire nuts, splices, or terminal labels while the cabinet is open.
Important Ordering Warnings
- This is a harness, not a loop detector.
- Do not use wire color alone if the old cabinet has been modified; verify each terminal by function.
Professional Advisory
Vehicle loop detectors and related wiring parts should be installed with the operator power off and tested with the gate, barrier, or door system in a controlled position. Do not bypass required safety devices. If the installation involves high voltage, damaged conduit, wet junction boxes, or uncertain relay wiring, use a qualified gate or access-control technician.
Product Questions and Answers
Is this harness used with Reno BX detectors?
Yes. The 802-4 style harness is commonly used with Reno BX Series 11-pin detector installations when the cabinet is wired for that connector.
Does the harness include the loop detector?
No. This is the wiring harness only. The detector, socket base, and loop wire are separate items.
Can this harness be used with AX and B Series detectors?
It may be used with compatible Reno AX, AX2, AX2DL, B, BX, BXC, and BX-LP detector families when the 11-pin pinout is specified.
Why replace the harness?
A harness may need replacement if the connector is cracked, loose, corroded, missing pins, or previously miswired.
Should the wire colors match the old harness?
Wire colors are helpful, but the final check should be the detector manual and operator wiring diagram, especially on older cabinets.
