What Is The Signal Coming From Speed Sensor To The Instrument Cluster

[Vilius]

Hello, it's not a trouble at first, only a question if anybody measured what is the signal that comes to instrument cluster.

I found out its pin 27 on the red connector, and ground wire is pin 7.

But is this a voltage increase, when speeding up?

Going to begin installing a DIY parking assitant kit, and there is a signaling wire to connect to speed indication.

BTW, mine gal has a simple radio installed, no Gala wire is there.

 

PS. is anybody done something with a similar DIY kit?

I still didn't think of how to wire 4 front parking sensor wires from cabin to the front bumper with no drilling.

Is there a easiest place to "penetrate" engine bay?

 

Thanks in advance.
