Update: 2017 Civic Hatchback Sport CVT WITH HONDA ACCESSORY REMOTE START
SUMMARY (roughly for people who don't want to read): Buy wiper switch part number 35256-TV0-A11. Take about a foot of 22-24 gauge wire and crimp pins on each end. One end goes into the Body Control Module's beige Connector "E" at Pin 21, which is an empty slot. The other end of the wire goes to the white Remote Start Control Unit's grey connector at Pin 8, which currently has a grey wire already in it. De-pin this wire and tape it back out of the way, insert your wire in it's place.
For people want more info- PDF attached for Honda Accessory Remote Start wiring diagram (Hatchback).
When you disconnect the wiper switch's connector, you will see that the wiring (colors) looks nothing like any of the pictures in this thread. When you have the Accessory Remote Start installed, part of the installation is putting in a new section of the dash harness. One function of the remote start is to electrically cut the wiper function. So your unattended vehicle isn't trying to wipe 2 feet of snow off and destroy itself or scrape the windshield if someone put something under your wipers. You could just do as this thread states and just remove the wire in pin 10 and run your own wire to Connector E Pin 21 of the Body Control Module, and this would most likely work as far as I know. But it might be a better idea to just remove the grey wire (Pin 8) at the Remote Start Control Unit, which is a white box very close to the Body Control Module. This grey wire at Pin 8 is stated as unused. You could pull the wire out of the harness and put a crimp connector on it and use it, but I didn't want to cut up my harness. So I simply removed it from the Remote Start Control Unit connector and installed my own wire from Pin 8 of the Remote Start Control Unit to beige Connector E Pin 21 (empty) of the Body Control Unit. This way the wiper's electrical cut functions will still exist for remote starting (it may be that pin 10 at the Remote Start Control Unit actually controls the wiper motion cut. Pin 7 may just cut the variable voltage input).
As stated previously for Hatchbacks, part number 35256-TV0-A11 was used.
2 wires were pulled from a donor connector, you might want to use about a foot of wire (or more) with the same crimp connectors on each end. The foot of wire is for the ability to disconnect those two different connectors and not have them bound tightly together by this additional wire you add. ****a better idea would be to add a bullet style connector in the middle of this wire you add so it can be disconnected in case of service needs****.
View of Wiper Switch Connector from the Accessory Remote Start wiring harness. Pin 10 (Light Blue) is already used and run down to the Remote Start Control Unit Pin 7. So there is no need to change anything up at the wiper switch connector.
The over exposed white box on the upper left is the Remote Start Control Unit. The metal tab behind the connector is to prevent the harness from unlocking and coming out. You just slide the box away from the tab and you can release the connector (metal tab blocks the lock on the connector). Don't forget to slide the box back when you are done. You can see that the grey wire is now unpinned and pulled back, it was taped up to the harness when completed. You can see the additional wire now in it's place. You also can vaguely see the new wire goes back to the beige Connector E in the background on the Body Control Module.
You can see Connector E (beige) on the Body Control Module Pin 21 now has a grey wire installed.
If you notice how close the Remote Start Control Unit is to the Body Control Module, you could just run a short wire across and have a simple 1 pin connector (bullet style) in the middle that is easy to disconnect if any service needs done. That is probably a nicer solution than coils of wire.
Low quality pics, but still could be usable to someone trying to find parts in salvage yards.
