3 Piece connector?

[fudge12]

Well after many months of having being robbed of my beautiful touchscreen head unit, i am slowly rebuilding the center console of the damages. I had the car parked up in a private garage for the past couple weeks so I don't have any access to check the connector blocks for the head unit wiring. Today I purchased a wiring harness. I see that this kit came with 3 connector blocks. How many blocks does the factory harness have?
i have an 00 v6 non-sport

from the second picture: the one on the right, you will use, main harness with power ground accessory and speakers

the one in the center, you will use if you have the factory subs, kinda sucks if you do because that brand doesn't have RCA connectors on it, so you will need to get one to attach if you have the subs.

the one on the left will not need to be used, that factory harness has the steering wheel controls wire in it, Ive always soldered into the factory side of the OEM harness for the SW adapters.
