Thread: Reverse & Neutral through Terminator X Max Transmission Harness

  1. #1

    Default Reverse & Neutral through Terminator X Max Transmission Harness

    Is it possible to get reverse & neutral signals as an output to run backup lights & neutral safety with the Terminator X Max, transmission & DBW harness package? I have a LS3 & 4L80E transmission.

    Default 4L80E Transmission Inputs

    Can anyone explain what the Pin (B22) Range B, (B9) Range C, and (B8) Range A in the transmission inputs for Connector J4 are for? Are they inputs that can be used to know what gear the transmission is in? Still looking for a way to create an output for Reverse.

    I think I understand what you're trying to do, but it might be simpler to use the external PRNDL switch that goes on the external side of the transmission, to get what you want. It my memory serves me well that switch ($20) has a reverse light signal ready to use.
    The inputs to the ECU on the round (internal) transmission connector are for the computer to check if the tranmission is shifting properly.
    See this picture: To compute that you are in reverse from A/B/C you need some kind of logic box to determine that. It'd be far easier to use the PRNDL switch.

    I'm using the NSS on my steering column for backup & reverse lights. Much simpler.
