Haltech RA8 - Manual

RA8 Instructions
Introduction
The RA8 is a new type of reluctor adaptor from Haltech that offers excellent noise
rejection, and the ability to piggy back to a factory ECU reluctor so a Haltech can be
triggered whilst maintaining factory ECU control of non-performance oriented items.
Pin-outs and Wiring
The RA8 has a 7-pin male connector attached to the extrusion, and a female receptacle
connector is supplied. The pin numbering of the connector is clearly marked on the
receptacle connector. Please ignore any numbering on the connector attached to the
extrusion.
HALTECH RA8
1. CHANNEL B INPUT +VE
2. CHANNEL A INPUT +VE
3. CHANNEL A & B INPUT -VE
4. GROUND
5. +12V SWITCHED
6. CHANNEL B OUTPUT
7. CHANNEL A OUTPUT
Generally channel A is used for the Trigger, and channel B for the Home, however the
channels are functionally identical.
Both reluctor coil negatives should be connected to the pin 3 reluctor input ground (or
just one if only one channel is being used). Connect the trigger coil positive to pin 2
Channel A In. Connect the home coil positive to pin 1 Channel B in. Connect a power
ground connection to pin 4, and a 12V supply to pin 5. Connect pin 7 Channel A Digital
Out to the Haltech trigger input, and pin 6 Channel B Digital Out to the Haltech home
input. Note that the Haltech should be set for normal input trigger, and not internal
reluctor adaptor, as the RA8 converts the reluctor signal to a normal trigger signal.
