Honda Dash Multplexor Module

This is a dedicated module that will allow the original dash functions of coolant gauge and battery warning light to work with aftermarket ECU’s. 

The battery warning and coolant gauge are both controlled by a multiplex signal that is usually generated by the Honda ECU.  When the original ECU is removed both of these functions stop working.

Our new multiplexer module emulates the original Honda signal, and controls the dash like a factory ECU.

A simple 4 wire design, it simply needs connecting to power, ground, ect signal and multiplex output. All of the wires you need are on the original ECU plugs, and easily accessible.  The modules internal software monitors the battery voltage and turns on the warning light under a set parameter, so no connection is required for the feature. 

For the module to work correctly you MUST be able to disable the ECT pull up resistor on the ECU, and enter the voltage/temp values provided with the kit. To control the OE dash we need to recreate an original signal, and the module has all of the correct pull up values built in to do this.
