carrier ducted O R W2 Y C

What does it all mean?
I think I've come across similar in a goodman, but they were easy to work out.
I've got a 38YCB036903 O/U, And a 40 QCA I/U.
Someone has cut the wiring to the Enerstat SHP-1 during renovations.
I've worked out what all the W1, Y1, G, R, O, B on the enerstat mean, but need to tie them in with the carrier terminals.

Also from the outdoor unit there is a small white cable connected to C,Y, O, W2 and R. ( black, yellow, green, white and red respectively)
At the indoor unit the cable from the outdoor is a 4 core different black cable, and only red, green, yellow and brown. So there's a join somewhere, but I'm sure that the interconnecting cable wasn't tampered with, just the thermostat cable. But any ideas how that would work!? Something to do with the fan motor not connected to the outdoor control board? Is that a normal set up?

Many more questions (extra relay hooked the the enerstat thermistor terminals?- might have something to do with the fan), but I'll sort out the basics first.

Thanks.
