Long story short. Got a good deal on a silo special that was gutted so I’m trying to get it back close to original. Found a Cutlass BFR loaded pick guard with the new style silent circuit that I want to use but after paying I noticed in the picture that there is no trem pot on this one like I see in other pics. I ordered a new silhouette special pick guard so I was hoping to drop in the already wired electronics and be done. Also the new guard is coming with no pot holes so I can use the cutlass guard as a template and drill my own. Can someone tell me if this silent circuit looks complete? Maybe the early ones didn’t have the trem pot? Any insight is appreciated.

That looks to be a different revision of the board that I've seen ... the pics you can generally find online have the trimpot where this board is marked with "TPA" (trim pot "A" I assume). Your board also has a "TPB" (assuming that's for a second one).

From the pic, I can't really tell what's at TPA & TBP (looks like a small connector, not a trimpot). Can you take closeup?

Looks legit. MC907W Rev1.2 matches what came stock in my Cutlass. I can post a pic later if you like but it's a pretty dead on match.

@beej , if you're referring to the rectangular shape on the edge of the board and to the right of TPA, it's just a blob of solder. Same as mine.

EDIT:
One other thing to note, look at the top right of the board by where you see V-. Attach the red wire from the battery to the 6th pad from the top. It's should be the one next to the "+" of V+.

Thanks. Yeah what I gather is the red wire from the 9v goes to the 6th solder point like you said and black from the 9v goes Ring on the TRS Jack, white goes to tip and ground (green) goes to Sleeve, correct?

Looks fine to me. TPA and TPB are trimpots that allow individual adjustment of the silent circuit for Phase A and Phase B (for the neck and RWRP middle pickups). The ground side of most normal single coil pickups goes to Phase A/B pads. The stock Cutlass pickups have a separate ground shielding wire that go to the two G pads (non-silent circuit ground). And yes, the + wire from the 9V battery goes to one of the two V+ pads.

I'll have to pop the pickguard off to be sure but I'm pretty sure that's correct for the other wires.

You seem new here so I'll tip you to the unofficial rule. Pics or it's not real. Let's see that Silo.
