USER MANUAL
Version 0.1 - 09 Jan 2022

Welcome to the Aha family!
Dear fellow EVian,
Congratulations for your Aha NexCruise! We are excited to share the delight and
freedom this system is going to bring to your driving experience!
The Aha NexCruise was born out of our own dire need to solve several pain points
with the entire experience of owning an EV. It brings a wealth of features which
empower you to very precisely manage the energy consumption of your EV, so you
can drive with full peace of mind even on uncharted roads. As a plug-and-play
system, you can install it in a fully reversible way without any modification in your
car.
Once again, we welcome you to our family, and look forward to creating more Aha
Moments together!
Yours truly, on behalf of the entire team,
HEAD, product experience.

Introduction
We have designed the system so that you don’t need this manual to operate it, but
for the sake of a ready reference, we hope you will find this work useful.

Know your NexCruise
Inside the box, you will find the following components comparison of your NexCruise
system:
The main unit
This is the main NexCruise unit, which does all the smart work.
It has four ports, which are denoted as NC-OBD, NC-PEDAL, NC-LED and NC-VCU. The
location of all these ports are shown below:
5

Dial with Base plate
The dial is used to control the various functions of the NexCruise system.
LED display module
This module shows the status of various functionalities, and state of the system. It
has a four pin connector, which we’ll call the LED-4P connector in the rest of this
manual.
It has five full-colour indicator lights, which, alongwith their most common functions
are shown below:
6

Cables
Let’s now identify and name various cables, and the connectors.
In-car ports and connectors
Not a part of NexCruise, but let’s first name and identify a couple of items in the car
for the scope of this manual, to understand things better.
Accelerator pedal port
This is a 6-pin Male port on top of your car’s accelerator pedal. Let’s call it the
A-PEDAL port.
7

Car’s VCU connector
This is a 6-pin female connector, a part of the wiring harness of your car, which
connects the accelerator pedal to the VCU of your car, and looks like the picture
shown below. For the sake of simplicity, we will call it the “CAR-VCU“ connector.
Now let’s talk about the cables that come with your NexCruise system, which
connect it to the rest of your car.
Extension cable
This cable connects the main unit to the CAR-VCU connector. Technically, it just
extends the CAR-VCU connector to a more convenient location, so we call it the
extension cable. Its two end connectors are a 6-pin male and a 6-pin female
connector. Let’s call them EXT-6P-M and EXT-6P-F connectors for future reference,
identified as follows:
8

Pedal cable
This cable connects the accelerator pedal to the NexCruise. It has two connectors,
6-pin female and 2x3 pin female. We’ll identify them as PEDAL-6P and PEDAL-2*3P
connectors:
Data & Power cable
This system connects the NexCruise to the OBD port. 12V power from the Aux
battery of the car, needed to power the NexCruise, is also supplied by this cable.
9

It has two connectors, OBD male and D-SUB female. Their identification and names
going forward are:
Bypass cable
This cable will be useful to bypass the main NexCruise unit, and connect the
accelerator pedal directly to the car (so it becomes the way it was without NexCruise,
electrically).
It has two connectors, 6 pin male and 2x3 pin male. Their identification and names
are shown below:
