Tried searching everywhere for where to ground the vtec solenoid...Whats the correct place or doesnt it matter if i ground it to chassis, ecu ground wire or is there a particullar pin on ecu ie P2T OBD2a ...

Grounds on ECU are pins
D12, D11 - sensor grounds

A22, A9 logic ground

A10 , A23 power ground

Or is just grounded it on thermostat housing or chassis okay?

Thanks

 

anywhere is fine

 

thanks man!!
