no need to hack OEM harness, T-harneses exist for plug&play remote start systems, check out idatastart. just hack the plug&play harness, the datasheet of the harness is included with pinouts.Pass on hacking up the harness to put directed / viper gear in the car.
honda doesn't let you, but you can if you know howI’m not sure the fob is always transmitting a signal. I’ve seen comments that it does & that it doesn’t. Maybe it depends on the manufacturer. It would seem that would really wear down the battery quickly.
The way I understand it, thief #1 touches the door handle which sends out a signal. His device transmits the signal to thief #2 who in turn sends the signal inside the house or garage & hopes to activate the fob if within range.
Thief #2 picks up the fob’s coded signal using his device which in turn transmits it to thief #1 who is standing at the car. His device picks up the signal & sends it to the car to unlock the door & start the car. Once the car is started you don’t need a fob, just don’t turn off the engine.
If the fob is always sending a signal then thief #2 just needs to pick it up from the house & transmit it to thief #1 at the car.

Take a look at the video where the thieves use the relay attack method.
This demonstration shows the driver going into a café for a cup of coffee & his fob signal is relay attacked & car stolen in 30 seconds.

Problem is that Honda does not let you disable the system.
Your secondary defense system is in your profile pictureSecondary defense systems might help. Things like an additional kill switch, or code reader needed to start the car, or steering wheel lock, etc. Just brainstorming. Open to ideas...

Since you were talking about Europe, it seems as though as only the US models/trims are affected: LX, EX, EX-L, Touring, Si, Type RNot very common in the USA at the moment but Canada and Europe have been fighting this for years.
