Wiring Harness Connections
Co
nnect the 8 pin connector in the main harness to the female end of each
O2 sensor harness.
If you purchased kit number 77062S, your kit includes a 2 1/16” digital
air/fuel ratio gauge. Locate the 2-pin gray connector in the gauge harness,
and connect it to the supplied connector and wiring for the main harness. If
your kit did not include this gauge, it is available separately through your
Accel DFI dealer. The part number for this kit is 77063S.
If you are connecting the control module to an Accel DFI Generation 7+
system, the 4 pin square male connector in the main harness will have a
corresponding female connector in the Generation 7 system harness labeled
as “HEGO”. These connectors should be joined as per diagram A.
If you are using the system as a standalone air/fuel ratio meter, refer to
diagram B.
If you are using the system with another manufacturer’s engine management
system, refer to diagram C.
If you have a dual exhaust system and are using the 77063 dual wideband
controller, please refer to diagram A1.
