Site only show T-Harness installation guide. Is there any additional wiring needed for the 05 Hyundai Sonata?

Wiring diagram came with EVO-ONE. But there is no other installation guides on the site other than the T-Harness installation. Does the 05 Hyundai Sonata only require the T-Harness and no other wires connected.

There are no other installation guides as your sonata does not have an immobilizer, (not sure if the EVO-ONE can be used as a conventional starter?) at the very least you would have to hook up the brake wire, but  for all functions to work they would have to be hardwired.

I installed the T-Harness, connected the ground and the (+) Brake Wire. When I connect the Evo-One the three lights on the unit flash mutiple times then quit. OEM key fob not working on unit but still operates door locks, alarm and trunk. I only want to use the remote start function.

I flashed the unit to the latest updates. And have Option 38.2 Enabled on the Remote-Start and Option C1 – OEM Remote Monitoring to ON on the Bypass.

I found this https://fortin.ca/en/features/3x_lock_remote_starter.html

It shows the OEM key fob as not being compatible with the Evo-One. Could this be the problem?

 

If you are trying to remote start the car with the OEM remote this is not possible as seen here: http://fortin.ca/en/vehicles/hyundai/sonata/2005/ The vehicle does not support 3x lock. The evo-one can be used but you would need to have an rf kit to make the unit function properly. If you wanted other features such as lock/unlock you would need to connect these wires to the car.
Ok thank you. Can you recommend a which rf kit to use?
FTX 64/44 or 75 Fortin RF kit will work like a charm with an evo-one:)
Hi again, Used  the T-Harness, connected  the 25 pin connector wires using the RF642W guide 33021 and programmed the key fobs. Doors, and alarm work. But the trunk does not release and the car will not stay running. Cannot locate where to connect the Dk.Blue (-) GWR wire. Should it connect to Disarm (-) from the factory alarm or a ground off the alarm relay?
 
Defaults and C1 Enabled on the Bypass .

Remote Start  Options-    2.1, tach -3 but no wire connected, 4.1, 6.1 & all Off, 7.1, 8.1, 9.1, 11.1, 12.1, 13.2, 14.2, 15.1, 16.5, 18.1, 19.1, 20.1, 21.1, 24.1, 25.1, 26.1, 29.1, 30.1, 31.1, 32.1, 33.1, 34 off, 35.1, 36.2, 37.1, 38.4, 39.1
Change option 20 to option 20.2 in the remote starter...this is your start and die problem.

Don't worry about the drk.blue wire it doesn't get used.

Trunk release is a physical connection in the car if you want ti to work.
Thank you, option 20.2 solved the shutdown after start.

About the trunk. I have the Trunk Release/Aux (-)Yellow/Black connected to the Trunk/Hatch Release (-)Green at the ETACM. Should It be connected somewhere else, or did I miss something in the options or key fob settings?
trunk release in this vehicle is ( + ) positive. so not sure what you have hooked up to but does not sound right to me.

Also if your gonna do it you'll need a relay to change the negative to a positive.
My apology. It was my mistake. I had it connected correctly, but I didn't realize I had to press the key fob button longer than I was pressing it. Everything is working as it should. Thank You again for your help.
