J124/125/126 are parallel connected and therefore interchangeable.
The same for J105/106.
Only difference I see is that the harness to the translite has also an YELLOW string ( =pos.3 + 9 on same connector with VIO + GRN)
Does that clarify the inconsistencies ?
Pinwiki has some nice pictures with path from J103 to J105

Quoted from MrSanRamon:no voltage to pins 9
more specific the yellow string:

When J103 / 104 / 105 / 106 are unplugged, it is easy to measure continuity from J103-4 to F112 to J105-9
