Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual
Harness Main Connector
The 30-way harness side main connector mates with the GEN3 ECU header connector marked with
“DAE”. This connector will only fit in one direction, but must be mated with the ECU header
connector marked “DAE”.
Note: It is essential that the DAE wire harness main connector be installed in the correct header
connector location on the ECU! Installing the DAE harness main connector to the incorrect
header location on the GEN3 ECU will damage the ECU and void the warranty!!
Analog Trigger
Connect the yellow wire to one end of a live (12V) two- pole On/Off switch. While logging data this
wire must stay hot (12V)! Mount the switch in an easily accessible location.
Note: The On/Off switch must be cycled (turned off then on again) between logging events in
order for a new log to be made!
When using DAE, the analog trigger wire becomes the data acquisition trigger.
Note: Since the DEA option has its own data logging “trigger” wire, the (DAI) timer enable wire
(L2) on the engine side wire harness can be reallocated to collect trans brake or clutch release
data.
Reallocating the L2 wire becomes particularly useful for capturing a “time zero” point for each pass.
