Xirgo I/O harness versions
This article describes Xirgo harness versions and their use in Xirgo installations.
There are two Xirgo I/O harness versions available:
- Updated I/O harness (MMID / part number 1100001061)
- Legacy I/O harness (MMID / part number 1100000682 (CBL-0040-TAA))
This guide also describes how to distinguish powered and unpowered Y-cables:
Updated I/O harness (MMID / part number 1100001061)
This harness can be used with a powered Xirgo diagnostic cable Y-cable (both the OBD-II type and the DLC type), and when installing our RFID Driver ID reader.
The powered Y-cable passes power to the I/O harness to supply power for accessories such as a Driver ID buzzer. Only use the white wire (J) if specifically instructed to do so by Verizon Connect.
(A) OBD-II 24 pin I/O harness (RFID compatible) connects to Xirgo device
(B) Input 4 - black/green wire (ground trigger)
(C) Input 2 - black/orange wire (negative trigger)
(D) Input 1 - purple wire (positive trigger)
(E) Panic/privacy - 4 pin connector
(F) Driver ID reader - 2 pin connector
(G) Garmin - 10 pin connector
(H) Driver ID buzzer - 3 pin connector
(I) RFID reader - 6 pin connector
(J) Software controlled ignition input/output - white wire (use only for vehicles with kill switch, or when specified by Verizon Connect)
(K) 3 amp fuse
Legacy I/O harness (MMID / part number 1100000682 (CBL-0040-TAA))
(A) 24 pin Molex I/O connector
(B) Driver ID reader connector
(C) Garmin connector
(D) Panic/ privacy button connector
(E) Driver ID buzzer connector
(F) Input 1 - purple wire, pin 6 (positive trigger)
(G) Input 2 - purple wire, pin 7 (negative trigger)
(H) Ground wire (black)
(I) Ignition power wire (white)
(J) Constant power wire (red)
(K) 3 amp fuse
(L) 3 amp fuse
The legacy I/O harness has two installation use cases:
- With a legacy unpowered Y-cable
- With a powered Y-cable
Using a legacy I/O harness with a legacy unpowered Y-cable
A legacy I/O harness can be used with a legacy unpowered Xirgo diagnostic Y-cable (both the OBD-II type and the DLC type).
Connect the 3-wire portion of the I/O harness in order to supply power to the Xirgo device.
Using a legacy I/O harness with a powered Y-cable
A legacy I/O harness can be used with a powered Xirgo diagnostic Y-cable (both the OBD-II type and the DLC type).
Join the legacy I/O harness's fused red wire lead from pin 1 to the fused white wire lead at pin 5 using a butt connector or crimp cap.
If a legacy I/O harness is paired with a powered Xirgo diagnostic harness, do not connect the 3-wire portion of the legacy I/O harness to vehicle power and ground. Doing so creates two sources of current to the device, and poses a risk that could result in thermal damage to the vehicle or device.
If you are uncertain of your use case, Contact Support before proceeding.
A powered diagnostic harness provides power to peripherals from the vehicles’ OBD-II port or DLC port by passing power via the Xirgo Y-cable's red wire at Molex pin 14 through the device and over to the I/O harness's fused red lead at pin position 1.
Installations with a Driver ID buzzer
When a Driver ID is installed using a legacy I/O harness and a powered Y-cable, the external Driver ID buzzer requires a 12V source to operate. To power the buzzer, join the red and white wires using a butt connector or crimp cap.
This connection is for installations without a full 3-wire connection that use the legacy I/O harness.
Distinguishing powered and unpowered Y-cables
There are two general types of diagnostic Y-cable: powered and unpowered.
- A powered Y-cable can power a device when it's plugged into the vehicle's OBD-II port or DLC port. A powered Y-cable’s Molex connector is populated at pin 14.
- An unpowered Y-cable cannot power a device.
An unpowered Y-cable’s Molex connector is unpopulated at pin 14. The Y-cable has a red wire that has not been inserted into the Molex connector and is covered in protective shrink tubing.
