This includes any method of installing the RF chip.
It's surprisingly simple. Here's how to, off the top of my head:
1) open the grip and disconnect the battery. Also disconnect the eye ribbon cable, the battery/trigger plug and then carefully unplug the solenoid cable.
2) Remove the battery and board. Set them aside.
3) unplug then unscrew the reg. Unscrew the reg ASA. Unscrew the two screws which hold the trigger frame to the marker body. Gently pull the body away from the trigger frame, making sure to grab the trigger return spring and set it aside. Pull the solenoid cable and eye ribbon out of the trigger frame.
4 optional) I find it easier to work on the solenoid when it's detached from the marker body. If you're not comfortable with being able to put it back with its gasket properly aligned then skip this step. Using a #0 phillips screwdriver, unscrew the solenoid from the marker body. Take the solenoid out and grab the solenoid gasket out from behind where the solenoid sat. Remember how it was oriented on the solenoid for when you go to put it back together.
5) Cut both solenoid wires about half-way down. Strip 1-2mm from all four ends. Take some heat-shrink tube and cut two pieces about 1/4" long, and put them on the plug end of the solenoid's wires.
6) Match up the red ends from the solenoid wire's two ends, and the red end from the RF chip's cable. Gently twist them together and solder. Slide the heat shrink tube over the solder joint and shrink in place using a lighter, match or heat gun. Do the same for the black wires. The solenoid cable should run through both ends of the heat shrink tube, with the RF chip cable running back up towards the solenoid.
7) Using a multimeter, test the conductivity from each of the red ends to its mate on the black end. If everything still conducts then you're good to go.
8) Plug the RF chip into the RF chip's cable. It will fit in the back nook of the trigger frame with the plug sticking up behind the solenoid into the marker body. Put the rest of your marker back together
9) Turn the marker on and verify that the solenoid still fires (clicks) without air. Leave the marker on and able to "fire". Turn off your pulse. Hold the power button on the pulse until the light slowly blinks green. Pull the trigger to fire the solenoid. The pulse's LED should blink green quickly. Go ahead and let go of the pulse button. Turn the pulse back on and stop the feed disc with your finger. Verify that the marker is sync'd by pulling the trigger. Each time you pull the disc should start spinning again.
