Where is the check connector located for adjusting timing on a 22 re motor?

The check connector for adjusting the timing on a 22R engine is typically located near the passenger side of the engine bay, often found near the firewall or on the driver's side fender well. It is a two-pin connector, usually with a yellow and black wire, that must be shorted to set the timing correctly. Make sure the engine is at operating temperature and follow the appropriate timing adjustment procedure.
