I just got done doing a swap and the speedometer does not work and vtec does not engage. I also have a check engine Light does any one have any ideas on what could be causing this issue??? Thanx
It's a B16a JDM motor ..... and trans... in a 98 civic ek hatch w. obd2-1 harness.. and stock ecu from b16a

 

Pull the codes first. The VTEC will not engage with the VSS (Vehicle Speed Sensor)not working.
