Because the car will shut off when you open a door?

pre-programmed run time. This is great for those short pit stops when you
would rather not shut OFF the engine"

You need to tap 2 CAN wires and you are done.

I will be installing the smartphone module this week when it arrives and will post my updates.

i need help with installing this kit on my 2014 gs350 I can’t seem to plug in the black wire (not the one that goes into the ecu) it is too far in for my hand to get to and idk how anybody would be able to get this installed in 15 minutes I tried and after 2 hours gave up with half my dash taken apart and still not being able to get to the plug. Very frustrating process and my hand is all scratched up and bleeding.

I don’t understand how people install this kit in 15 minutes just taking apart the dash takes longer. Also I wasn’t aware that we had to splice any wires? I thought we just have to plug 2 things into the car and then program it. Any help is greatly appreciated

I am sorry you are having trouble accessing the the steering lock wire to insert the T-Harness. When you took off the trim panel under the steering wheel, did you unplug the push to start button, parking brake, etc. to allow you to move the panel out of the way for easier access? For me this connector was not too difficult, but I do have slender hands

no I left those on I guess this is why I couldn’t get a good angle.. I just have no experience taking off trim panels and didn’t want to break anything in this car. My other problem is I’m not sure what you mean when you said tap two can wires? What does tap mean and also idk what can wires are. Thank you for the quick response.

I completely understand being careful and cautious on these cars, things are expensive to replace and I never like to rush with something I am new to either.
To tap a wire means to make a T style connection where the main wire stays in tact, and you attach a second wire onto it, in the shape of a T (basically inserting it into the circuit without breaking the existing circuit)
The CAN wires I referred to are CAN BUS wires here is a short explanation. "A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each others' applications without a host computer" https://en.wikipedia.org/wiki/CAN_bus
If you dont have an easy way to tap into the thin wires (i personally dont like cutting the insulation and just tapping it together) I suggest these connectors from Amazon, easy to use a create a reliable connection
Amazon Amazon

thank you for the reply, I guess the reason I’m confused is I’m hearing mixed things about this remote starter. Some of the Amazon reviews say it was 100% plug and play and others are saying there’s splicing involved. As far as I know all I need to connect is the ecu and the black connector that’s by the steering column. Would you be able to provide more info on exactly what wires I need to connect to the car? I bought the kit off amazon for $150 and if has the T harness which is what I thought was all I needed for this to work. Thank you again

How long do you think this should take from start to finish also any tips on how to disassemble the dash more than I did because I’m not sure how to take the dash apart to have better access and don’t want to break any clips

This is the kit i have. There should only be 2 connections to the car itself? i dont see any wires that id have to splice.

If you scan the QR code on the box or go the MPC website and download the TIP sheet, it describes what two wires you will use from the bundle on the T-Harness side
