I’ve installed a new headunit and everything is working great except the pop up warning that I haven’t connected my speed wire.
I haven’t had any luck finding it in my car. The original radio harness doesn’t have a pin for one. Can someone point me in the right direction?
I have a 2017 Honda HRV
Thanks!

 

Speed is going to be on CAN bus. Should already be at the head unit harness.

 

It is not unfortunately. The stock radio has no speed enabled features. I have checked the harness pin outs.
The only place I see a speed pulse wire is off the ecu plug but I’m not sure I want to tap into that.
