Holley Dash w/ PSI harness. Question? Hello,
I'm building a kit car & I already have an LS2 with a PSI harness/computer. I'd like to use the Holley 6.86 pro dash. This my first LS engine and I've never had to deal with can-bus connections before. I called PSI & spoke with them about what I was doing with their product & they told me to look for a dash that plugs into the OBD port that their harness should have, but Holley doesn't show an OBD port adaptor.
Can I use the Holley 6.86 pro dash with my PSI harness or should I be looking at a different product?
Thanks!

You just need the standalone pro dash part #553-117. It works with anything and uses its own sensors.

you sound like my gf nitpicking on technicalities lol
OP asked about obd comms which was the context of my reply.
let me rephrase
Sounds like you are using an oem ecu which the Holley dash is not compatible with. The Holley dash only communicates with Holley ecus. if you want to add a whole new set of sensors, or tee into what you already have, you could use a holley (or many others but the holley pro dash is really nice) dash as a standalone.
