RX50 Dis/assembly..

I'm really embarrassed, but guess what? I took apart my RX50
(cleaning/servicing..) but didn't bother to document where all the
jumpers/headers go..

Well, when I try to put it back together, there's just 1 3-way header
left which has THREE posibilities (board has 3 instances of 3-way male
headers), and I don't know which one to put it to.

The said 3-wire (red, blue, yellow) header originates from the optical
slotted switch which detects (I think) the end of the tracks. It will
terminate to one of the 3-way male headers at the SEEK/INTERFACE
backboard (which is perpendicular to the main metal chassis.

Here's some ASCII art of SIDE1 of the SEEK/INTERFACE backboard with all
the headers:
                                      A B C
                                      V V V
+------------------------------------------------+
| ++++ +++++ +++ +++ +++ |

So the question is, does the slotted switch cable terminate at headers
A, B, or C?
