Method 3: Connection Via Analogue output to Non Haltech CAN Supported ECU
The Haltech CAN Wideband Controller is able to be used with ECU's that do not
support the Haltech CAN System.
To enable the Haltech CAN Wideband Controller to function as an analogue device
please connect the harness as described below:
•
Connect the Red wire labelled "+13.8V Battery" to a + Battery Fused source (7.5A fuse
minimum) or directly to the Battery + terminal
•
Connect the Black wire labelled "Ground" to Battery - or the chassis of the vehicle.
•
Connect the Red wire labelled "Gauge Power" to a +12V Switched Ignition
•
Connect the Black/White wire labelled “Signal Ground” to Battery - or the chassis of the
vehicle.
•
Connect the White wire labelled "CH 1 Output" to any available analogue input on your
NON Haltech CAN supported ECU
•
Connect the Grey wire labelled "CH 2 Output" (only available to WBC2) to any available
analogue input on your non Haltech CAN supported ECU
•
Calibrate the AVI input in the ECU software as:
•
0V = AFR 10
•
5V = AFR 20
Your Haltech CAN Wideband Controller can now be used with earlier
Haltech NON-CAN based ECU's.
