Popeye sorry bud, it's probably because i'm working without a manual, the only thing I have is the "power cable" schematic and a few diagrams. On the "power cables" page, there is a "4REC B" on the bottom right of the page. It is physically mounted on the bottom right corner of the contactor panel (inside where you stand). It was the only rec I was seeing but now that Ifixit has helped me locate the other ones I see exactly where you guys are talking about. The RECs are all located next to the capacitor.
