Other Consumables - zip ties, electrical tape, solder

Total cost (outside of consumables I already had on hand): $234.45

Total time to complete approx. 10 hours, but I was slow and methodical and had to do some additional reading to figure out some wiring and the flashing and programming of the unit. 21 wiring solder connections to make. I highly recommend solder vice vampire/ "T" taps for wiring connections.

 

Pre-installation:

1) Remove cartridge slot dust cover on the bottom of the CM-900.
2) Insert BladeAL cartridge into the bottom of CM-900. Be careful not to bend any of the electrical contacts.



3) Cut and tie back any UNUSED wires on harnesses to CN2 and CN3. USED wires on CN2 and CN3 harnesses are boxed red in the illustration of the next post. I left approx 3 inches on unused wires, tied back, and insulated in case I ever have to use them in the future. Wrapped harnesses with Tesa tape up to a certain point.

The following YouTube video was somewhat informative:

Installation:

1) Disconnect negative battery terminal
2) Disassemble driver's side lower dash, lower shroud of steering wheel, and driver's side kick panel. I won't go into the steps necessary for this as there is plenty of documentation readily available on the internet.
3) With access to wiring/ harnesses you can begin installation.

 

Connect CN1 wiring:

CN1 - 8 PIN /// OEM - 8 PIN (under steering column)

1 - Red /// White
3 - Red/Wht /// Light Blue
4 - White /// Gray
5 - Blue /// Black
6 - Yellow /// Dark Green
7 - Green /// Light Green
8 - Black /// Ground (Bare Metal)





CN1 - 8 PIN /// Connector with gray release tab (under driver's kick panel/ same connector as horn wire)

2 - Grn/Wht /// Green

 

Connect CN2 Wiring:

CN2 - 20 PIN /// OEM - 7 PIN (under steering column)

1 - Gray/Red /// 5 - Blue
2 - Grn/Red /// 4 - Light Blue
5 - Orange/Black /// Ground (Bare Metal)





CN2 - 20 PIN /// OEM - OBDII Port

6 - Brown/ Red /// 6 - Purple
16 - Brown/ Yellow /// 14 - White

 

Connect CN3 wiring:

CN3 - 12 PIN /// OEM - 20 PIN (under steering clumn)

4 - Black /// Ground (Bare Metal)
6 - Orange/Wht /// Gray




CN3 - 12 PIN /// Blue connector (under driver's kick panel)

2 - Blue/Grn /// 14 - Light Green
3 - Blue /// 16 - Pink

 

Connect CN3 wiring:

CN3 - 12 PIN /// Connector with gray release tab (under driver's kick panel/ same connector as parking light wire)

7 - White /// Purple (horn)

 

I installed the safety switch earlier in the install using a drill and unibit until the switch would slide in and I could put the lock washer and jam nut on the under side to secure it in place. You will have to adjust the height accordingly. I ran the Gray/Black wire from CN3 out of the firewall boot into the engine compartment and wrapped it in loom.

CN3 - 12 PIN /// Hood safety switch

8 - Gray/Blk /// Hood safety switch terminal (used red crimp lug)

 

CN3 - 12 PIN /// Brake Pedal Connector

9 - Light Blue/Wht /// Orange



CN3 - 12 PIN /// OBDII Port

12 - Yellow/Blk /// 9 - White

 

Wiring complete!

From here, I used the Tesa tape and wrapped everything up nice and tidy. I mounted the antenna in the upper left corner of the windshield and ran the wire down the A pillar to the control unit. I mounted the control and Drone units in the locations I wanted, dressed and zip tied the cabling to the units, making sure nothing was going to snag and break or rub causing a short circuit, and reinstalled the trim pieces removed for installation. DO NOT connect CN1 thru 3 to the control unit at this time! Your computer will not recognize the control unit when you go to program it.

 

WARNING! Ensure your laptop is plugged into an outlet. The loss of power during a firmware update AKA "flash" could result in "bricking" your device (remote start control unit).

Flashing and Programming:

With CNs1 thru 3 disconnected and your laptop/ computer on, plug in the Autopage flashing interface USB side only to your laptop. Lt your laptop discover the device. Wait for the prompt telling you it is installed and ready for use. Plug in the other side of the Autopage flashing interface to the control unit CN6.

Using Internet Explorer Login to:

https://www.idatalink.com/

Create an account. Just make up a company name, select independent installer (or something like that), and your email. Confirm your account via the email they send you. Login.

You may have to update your plugin version (I did). Current version is 6.3.6. It should prompt you to update if your are not.
When that's complete, click "Flash your Module" in the upper right hand corner of the web page. Use the drop down menus to select Make, Model, Engine, Trim, Etc... It should bring up the correct firmware and prompt you to start (or something like that). It will prompt you it's complete and the flash is successful. Disconnect the CN6 connector from the control unit and put away your laptop.

Plug in CNs 1 thru 3, 5, 7 and 8 to the control unit. Reconnect negative battery terminal on the vehicle and make sure the hood safety switch is engaged. Follow the following programming sequence:

 

Download the DroneMobile app from the App Store and check functionality of both key fob and phone app. Enjoy!

 

How well does the keyless entry work? Assuming it means what I think it means - if I pull on the door with the key fob in my pocket it will unlock?

 

Sorry. Not that keyless entry. You still need to click the unlock button on the fob.

 

Got it. I was thinking of proximity locking. Compustar does have those options though!

Yeah, I looked at that system and deemed it too pricey for my needs. Proximity unlock would be nice though.
