EVO-ONE Installation in CAMRY 2026

Question

I have purchased the EVO-ONE  kit along with the T-Harness and Flash Link tool, and I'm planning to install it in a 2026 Toyota Camry Hybrid.

While reviewing the installation manual, I have a few questions I'd like to confirm before proceeding:

1. Cutting the (-)IMI wire: The diagram indicates that the (-)IMI line needs to be cut during installation. Could you please explain why this step is necessary? Is there an alternative method to complete the installation without cutting this wire?
2. 54-pin connector: Could you clarify the purpose of the 54-pin connector shown in the diagram (labeled as the black connector behind the driver's kick panel)?
3. ECU behind glove box: Could you also confirm what this ECU (referenced behind the glove box in the diagram) is used for in this installation?

I want to make sure I fully understand each step before starting the installation. Thank you for your help — I look forward to your response.

Answer 1

1. Imi must be cut. The module is taking over temporatily providing key data.

2. the 54-pin is simply a connector located in the vheicle. It has no specific purpose aside from routing wires in the vehicle.

3. The ECU is where the t-harness connects to. It provides CAN and ignition/starter circuits. The wire-to-wire guide shows which circuits are being used at the ECU. https://fortin.ca/download/118441/EVO-ONE_IG_REG_BI_TOY-CAMRY-HYBRID_PTS_2025_A_118441.pdf
