So, I've been asked about any pointers I might have when installing the Pinball Life EVO BriteCaps. Here is my best effort to document the process. Before starting I recommend placing a towel over the playfield to protect it. BTW, this same process can be used to remove the pieces you need to replace the rings (I did have to cut the zip ties from the top ramp to get the access I needed however - no biggie, just took lots of pics beforehand and redid zip ties when putting it all back together).
-1) Remove the cow ramp by removing the 2 post screws and the 2 ramp flap screws. Be sure you use a screwdriver with the correct size head so as not to strip the ramp screws. When replacing the 2 ramp flap screws, make sure the heads are seated below the metal flap. You may have to use something thin and non-abrasive to "pop" the flap up over the head when you are re-installing.

-2) Remove the right wire frame. Pay careful attention to the center mount screw as there will be a zip tie that will come loose from this. When re-installing, be sure to first put the ramp in position and slide the zip tie back over the post.
a) Remove the nut and washer from the right lower sling.

b) Remove the screw from the center support.

c) Carefully slide the two wires from where they are seated into the metal bracket attached to the top ramp. Note that you cannot fully remove the wireframe since wires are attached to it, but carefully set it out of the way and be careful not to scratch anything.

-3) Loosen the top ramp so that you can maneuver it around enough to replace the pop caps You do not need to fully remove the top ramp, but if you do you will need to cut all of the zip ties off and disconnect cables - I highly suggest not doing this.
a) Remove the nut and washer from the post securing the top ramp above the 3 pop bumpers.

b) Loosen the top gate nut and remove the lower gate screw securing to the plastic, then rotate the gate so as to access the ramp flap screws. Also, remove the 2 ramp flap screws as performed in step 1.

c) THIS IS CRITICAL OR YOU WILL DAMAGE YOUR PLAYFIELD AND/OR CABINET | 1) Use a small bag or sock or something to wrap around the upper ramp flap. When maneuvering the ramp around you could scratch the playfield with the thin metal piece. 2) Do the same to cover the metal support bracket at the right of the top plastic ramp. This piece is sharp, and it will scratch your side blade/panel or even the top of your side rail as you maneuver it around.

-4) Maneuver the top ramp so as to access removal of the 2 screws on one of the pop caps. You may have to hold it up or to the side (or have an assistant do it) to keep it out of the way depending upon which cap you are replacing. Be careful not to scratch the underside of it with a screwdriver or other tool while working to replace the caps.
a) Remove the two screws, and set them aside as you will be using the longer screws supplied with the BriteCaps to re-secure the caps after installation.
b) Remove the LED bulb.
c) Insert the new BriteCap module and orient it so that the screw holes line up with the holes in the housing, and the two small adjustment screws on top of the BriteCap are accessible (i.e. not covered up by the ramp to where you can't get to them).
d) Repeat the process for the other two pop caps.
-5) Turn the pin on in order to adjust the brightness of the outer rings and to set the inner rings to be solid or triggered by vibration. The document that comes with the caps will tell you which adjustment screw is which, or you just turn one to see what it controls. You'll need a fine tipped Philips screwdriver to turn these screws. You only need to turn slightly to achieve change, so don't over do it.

a) Find which screw controls the out ring brightness. Turn this screw to adjust to desired brightness (I have mine at 100%). Perform this for all 3 caps, as you'll want them to be equally bright, I assume.
b) Turn the other screw to desired setting. If the inner ring is currently on, then it will always be on. If you want it off by default and triggered by vibration then turn the screw slightly until the inner ring goes off. When set to the off position, the inner ring will flash during vibration (i.e. when a ball activates its pop). When adjustments are completed, turn the game off.
-6) Using the longer supplied screws, secure each of the caps by carefully aligning all of the holes. Tighten the screws until the caps are snug and don't vibrate, but don't tighten so much that you strip the holes.
-7) Install the top ramp.
a) Position the top plastic ramp back in place over the post and align the ramp flap holes. Insert and fully tighten the two top ramp flap screws, making sure that the heads rest below the metal flap.
b) Reposition the gate and insert the screw and tighten to secure the bottom part of the gate, then tighten the top nut of the gate.
c) Place the washer and nut back on the support post and tighten.
-8) Install the wire frame.
a) Insert the 2 wires into the support holes on the metal bracket attached to the upper ramp.
b) Place the bottom of the rap over the sling post but do not add nut back yet. Loop the zip tie over the center post to secure the wires, then insert the center post screw and tighten.
c) Place the washer and nut back onto the sling post, position the wire frame so that it is aligned with return lane, and tighten nut.
-9) Install the cow ramp.
a) Position the ramp in place and secure the 2 ramp flap screws fully. Again, make sure the heads of the screws sit below the metal ramp.
b) Insert and tighten the two post screws to secure the ramp.
ALL DONE! Turn the game back on, and enjoy your new PBL Brite Caps.
