PPG Sequential Gearbox Wiring and Configuration
Configuring and
Wiring a PPG Sequential to work with a Haltech ECU
This guide is based around a PPG 6 Speed Sequential as used in R32-34
Skyline GTRs, and how to configure it for use with a Haltech ECU.
It assumes the gearbox has been supplied with PPG's 'Universal Display
Harness' and the PPG gear display is being used. See note at the end of this
article about wiring without the use of the included gear display (for
use with a display dash for example).

Position Sensor Programming
The position sensor in the gearbox is
programmable, and must be configured to give a reliable signal output for use
with your ECU.
- Download and install 'BladeCom' software (see link
below for download)
- Connect the included USB programming dongle to your
laptop, then connect the Deutsch DTM plug to the 'Comms' connector on the
PPG harness.
- From within the BladeCom software, open the 'Sensor
Options' menu and choose 'Detect Sensor'
- Ensure the BladeCom software has detected the sensor by
confirming it shows a sensor version and serial number in the lower bar.
- Enable changes to the sensor by choosing 'Sensor
Options' > 'Allow Changes'.
- Choose 'Output Options' and tick 'Reverse'
- Select the 'Manual Setup' tab and configure all values
as follows. Click 'Set' after each entry.
- Once complete, return to the 'Sensor Options' menu and
untick 'Allow Changes'.
- The position sensor is now programmed and you can
disconnect the programming dongle.
- Programming of the PPG gear display is now required,
see the PPG Installation guide for instructions on this process.

Gear Display
The PPG gear display includes a power supply that provides the gear position
sensor with a regulated 5v supply. If you do not wish to use the PPG gear display,
then 5v must be supplied externally.
The easiest way to provide 5v to the PPG sensor is via the 'Comms' connector
on pin 4. Connect this to your ECUs 5v output. The 12v supply into the 'Chassis
Interface' of the PPG harness is now no longer required.
