Haltech HT051462 - Manual (Page 5)

Trim Module Connector
The Trim Module connector can be used in conjunction with the optional
Haltech Trim Module ( #HT010502) to make quick manual adjustments to
the Boost level / Fuel Injection Times and Ignition Timing depending on software setup.
Only one option can be adjusted at any one time with the single Haltech Trim Module.
Alternatively this connection uses Analogue Voltage Input 2 (AVI2) which can be
used / wired as a standard function input if required.

Fuel Pump Output (O/L)
Fuel Pump Output supplies a continuous +12V DC supply to the fuel pump when the
engine is running. This output wire is rated for a max continuous current draw of 15A .
The Fuel Pump Output wire can be connected directly to the positive side of the fuel
pump, providing the pump in use will draw less than 15A of current under full load.
If your pump will draw more than 15A or if dual pumps are to be used it is
recommended that you use this wire to control a relay to turn on the fuel pumps.
