# Tailgate Foot Activation (MARK 2/3)

## Packing List

1. Foot Sensor x 1
2. Signal Harness for Hatch Area x 1
3. Foot Sensor Harness x 1
4. Decoder Harness x 1
5. Long wire harness x 1
6. Small controller x 1
7. Decoder x 1

## Recommended Tools

1. Fishing Tape
2. Electrical Tape
3. Pry Tool

## Installation

### Step 1 - Removing the trunk panel

Open the trunk. Release the clips at the upper corners, then work around the trim to release the clips that attach the trunk trim to the trunk lid. 

{% hint style="warning" %}
Support the trim while releasing the clips, as the power trunk switch harness is still connected to the trim.
{% endhint %}

Disconnect the connection from the closing button

### Step 2 - Connect the signals in the hatch

Take out the signal harness.

Connect the external release signal connector. The connector is located in the middle, unplug it and plug the connector to our bypass connector. Plug the other end of our connector pair back to the car.

On the same harness, there is a 5 pin connector, connect it to the small module given. Stick it to the inner wall inside the hatch.

The remaining bypass pair is for the trunk closing button. We will do it when we reassemble the hatch panel. Note: this connector pair need to be connected in order for the foot sensor to function.&#x20;

### Step 2 - Run the wire to the trunk

Now run the remaining long wire down to the trunk. In order to do that you will need to run the wire down through the grommet. If it's too difficult to do so, you can run it along with the grommet.

Continue to run the wire until you reach the trunk sill. Connect the two pin connector to the foot sensor harness.

### Step 4 - Run the wire to the front

Get out the long 2 pin wire. This is an extension wire that you will need to run from the back to the front. Run it along the floor and tug it inside the trim until you reach the front right side of the car.

### Step 5 - Conenct Power and CAN Cable

#### **For Variant A**

Refer to **"Method 1 - Power & CAN Connection on Intel MCU"** from the following guide.

**For Variant B/C**

Refer to **"Method 3 - Power & CAN Connection below Right A-Pillar" for CAN Signal** and **"Method 4 - Power Connection at Low Voltage Battery" for Power** from the following guide.

### Step 6 - Connect and Set Decoder

Connect the decoder. Make sure you set the 1 and 2 of the switches on the decoder to "on".

Connect the long harness to the decoder harness by the 2 pin connector. Keep the 3 pin connector idle for spare use.

In the back of the car, connect the 2 pin connector of the same wire to the foot sensor harness wire.

### Step 7 - Run the foot sensor wire down and connect the foot sensor

For foot sensor mounting, refer to this guide below.

[Tailgate Foot Activation Kit](/evoffer-installation-guide/model-3/electric-tailgate-mark-2/trunk-foot-sensor.md)
{% endcontent-ref %}

### Step 7 - Test the foot sensor

Now you can test the foot sensor. Try to test if the foot sensor get deactivated when the car is in car wash mode, when the emergency flash light is on, and when the car is not in Park mode. Reassemble everything after testing.

{% hint style="info" %}
You might find that the foot sensor trigger the trunk open but it close right after raising a little. This is because the foot sensor logic need time to reset after closing. After the trunk close, there is a 10 second reset time before a kick sensor opening can work again. Try to wait for 10 seconds and do the opening, it will function again.
{% endhint %}

## Troubleshooting

Q: The foot sensor does not work.

{% hint style="info" %}
There are several things that you can check. First is to make sure the bypass connector on the trunk closing button is connected. Also make sure you connect both end of the long harness.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://evoffer.gitbook.io/evoffer-installation-guide/model-3/tailgate-foot-activation-mark-2-3.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
