I installed the Cliffy Munchkin PF protector yesterday.
Not too tricky, except for 1 discrepancy between my machine (ECLE #196) & both the Cliffy & JJP manuals.
A heads-up to you, in case this applies to you.
There was no 2-pin connector under the PF for the black & violet wires. My machine had 2 pairs of black & purple wires snake up through the small hole. I thought perhaps the connector shown in the Cliffy documentation had simply been stuffed up through the little hole & I'd see it on the topside upon Munchkin PF removal.
Upon removal of the Munchkin PF, I found those 2 black & 2 violet wires terminated in this little 2-pin 90-deg connectordoodle under the "W" in RAINBOW. See red circles in images below. There was enough slack to pull the Munchkin PF up a bit & then undo this connector here, so it worked out fine, but I did scratch my head for a while on this one.
Installation was otherwise straightforward. Took less than an hour, with 2 phone call interruptions & being stumped by The Case of the Mysterious Missing Connector.
While I had it off, I put a new band on that sideways sling under the O-Z rollovers & did some light cleaning.
