DO NOT output a voltage that can be directly measured as
conventional oxygen sensors do.
6. Wiring Installation
Black – Primary Ground
Red – Primary Power
Orange, White, Blue, Pink – Sensor Specific wires
Yellow – Analog Output
Black with white stripe – Analog Ground
The Yellow & Black/White Analog wires are unterminated and
wrapped under tape in the harness. Follow these wires from the
AFR500v2 connector and remove the tape holding the ends in place.
Once exposed, the analog wires may be used as-is or extended with
high quality butt connectors to another device.
A fused, red wire with a #8 spade connection is provided to connect
to a switched power source. This power source should be capable of
supplying 3A and should operate between 11v – 28v. Ideally this
source will be above 13v during operation. Any extensions of main
power should be 16AWG or larger with a high quality butt connection
and properly validated crimp joint.
A good, noise free ground is critical for best performance
. A
black wire with a #8 spade connection is provided to connect to a
reliable ground source, ideally the battery. If the analog output is
used with an onboard logger or ECU, the analog ground and main
ground should be connected to the same location to avoid a ground
loop or offset.
If the analog output is used with a tuning device such as an HP
Tuners, EFI Live, or similar system, the analog ground should be
connected to the tuning device’s analog ground. In cases where the
analog ground is connected to a tuning device, ECU, or logger, the
main ground should be connected to the battery or chassis. Any

extensions of the main ground should be 14AWG or larger with a
high quality butt connection with both AFR500v2 main ground wires
and a properly validated crimp joint.
Avoid high temperature, high vibration, sharp objects and ignition
components when routing the wiring harness.
If you wish to install the AFR500v2 across a firewall, it is relatively
simple to de-pin the Deutsch connector at the AFR500v2 controller. If
the numbers on the back of the Deutsch connector are unreadable,
TAKE PICTURES and NOTE THE WIRING POSITIONS. The
orange wedgelock can be removed from the front of the connector and
the terminals de-pinned with a small screwdriver. Be sure power is
disconnected when doing this and take care not to bend any wires.

6a. Dyno Specific Wiring & Grounding
Improper grounding will cause serious problems, including damage to
your AFR500v2. The dyno frame or chassis must be connected to
building electrical ground in accordance with National Electrical
Code (NEC) requirements.
Vehicles operated on a chassis dyno will generate considerable
electrostatic charge. The vehicle must be grounded to the dyno frame
while in operation. You can use a length of 16 AWG wire with one
end secured to the dyno frame and the other end equipped with a
heavy duty alligator clip that is attached to the vehicle frame or other
vehicle ground point. Failure to ground the vehicle will lead to
