Using a small point pick, pry the pin lock upwards while pulling the wire out of the connector.
Be sure not to damage or deform the factory pins.
This guide shows the use of the factory pins in the RDX injector connectors. These pins WILL work, however they do not lock in place. If you choose to install the RDX injector connector pins (sold separately,) do that now.
Disconnect the fuel line from the fuel rail by pressing on the release clips.
Once the line has been disconnected, turn the fitting upward to prevent more fuel from spilling.
If the vehicle has been running within the past hour, the fuel system could still be holding pressure. When disconnecting the line, be sure to have plenty of towels for any fuel spray or spillage.
Insert injectors into the ports of the fuel rail. Make sure the wire harness connection clips are on the opposite side of the fuel rail mounting points.
Fuel or a small amount of oil applied to the o-rings will ease the installation of the injectors into the fuel rail.
Install the quick disconnect fuel line connection clip.
Jason, you can swap out the injectors and keep the OEM fuel pressure, however is isn’t going to work as well without actually retuning the car. You should use KPRO and have the fuel trim / injector size adjusted accordingly.
