Holley Terminator X does it work?

Connectivity

Hi
Is it possible to hook up realdash with Holley terminator ? I can not see Holley is supported but m taking a chance to ask.I have two can bus connection on my wiring harness. One going to the small 3.5 dash and the other to an USB male connector going to a laptop. Is it possible to use an adapter going from USB male to female > Male and the into a Android tablet ? Im only interested in showing the same gauges that I get in the laptop in the Holley v3 software. Holley has a USB/BT device with gauges but its only released in US and Canada. I thought this could be something cool if it works,

regards Rob

Yes, to my knowledge many people are using RealDash with Terminator X ECU using a CAN connection.

Thats sounds great, what type of Can connection would best to use ? And is it possible to connect directly to the USB cable comming from the master harness ?

Basically any of the RealDash supported CAN adapters will work:

RealDash | Manuals | Supported CAN/LIN Adapters

We are currently mostly using SLCAN type adapters. The Waveshare and Seeedstudio styles are also popular.

Yes, it’s possible. You will need:

  • a Terminator X splitter
  • a USB to CAN converter cable for Raspberry Pi 5
  • a Raspberry Pi 5
    Ask a GPT chat user for the connections

Well, most you mentioned above is actually not true, but welcome to our forum anyways.

  • No splitter required, connect CAN adapter directly to ECU CAN H and CAN L wires.
  • Raspberry Pi 5 is not a requirement, any device running RealDash is ok, except for iOS devices which do not allow direct USB connections.

That cable is Holley proprietary connection cable. Unfortunately Holley does not disclose its protocol, hence it cannot be used with other than Holley software/hardware.

So this is the connector to get ?

And convert USB to USB-C for the tablet ?

Correct. I’m not familiar with Holley wiring connectors, but if you wire ECU CAN L and CAN H into corresponding screw terminals on the adapter, you should be good to go.
