The 6 wire unit seems to me like each LED has both wires out the bottom for each, but the 4 wire unit has a wire for each LED and a common for all. 10Meg is not the value of those resistors, unless you read them with an ohmmeter to confirm, The blue body resistors and their color bands are very hard to read, the colors just don't look right. They may be 1K. You can use your ohm meter to check each pair of wires in the 6 wire unit and find which pair of wires is going to an LED, it will read like a diode, only one way. The same for the 4 wire unit, but you will have to first find the common wire, by going from the common to the other wire looking for that one way conductivity. That may take a bit of hit and miss to isolate the common. Once you have that determined, you will have to power them up to see which pair of wires lights which LED in the 6 wire, and with the common hooked to the PS, which of the remaining 3 wires lights which lamp in the 4 wire unit. Be sure to mark them for ID.
