    Has anyone used the trans brake control feature? Is the output pin that is used power or ground ? Trying to figure out how to wire in the solid state relay that I'm using.
    Thanks

    I don't know of anyone using it yet. The output pins are ground. High Current Out 3 would be ok to use.

    Im not getting a high current out 3 (negative)
    Have the aldl 3 grounded to my trans button. Launch & trans brake set to dig switch 3 transbrake out set to high current out 3. Nothing comes out of the high current 3(negative) when i hit the button.

    I thought it was pin 2. Should be white with black stripe wire

    I tested the aldl wire at the ecu White/ black line. has ground signal when you hit the button. went to test mode and tested high current 3 out. it send ground signal out. ecu set to digital switch 3 on launch, transbrake set to same as launch. tranbrake output set to high current out 3. ecu isn't send the signal when I hit the button out threw the high current ou 3t. is there something that needs turned on.. I am running coil on plug. im missing something and it prolly right in front of my face.

    Yes.
    Also have aftermarket shifter so. So gear selector isnt accurate. Dont know if that has something to do with it
    im horrible with wiring.

    Made a temporary connection to 18 on the 22 pin switched to dig switch out 2 Bam. It works. So i have a problem with dig switch 3 moving ground to high current out 3 when button is hit

    Here's one example of how it could be wired. If you can't get the ALDL input working for some reason. I can test the ECU if necessary to see if I get the same result.

    Did you pull the plugs out of the computer and confirm your aldl wire is going to the correct location?
