Installation of Haltech Products

No responsibility whatsoever is accepted by Haltech for 

the fitment of Haltech Products. The onus is clearly on 

the installer to ensure that both their knowledge and the 

parts selected are correct for that particular application. 

Any damage to parts or consequential damage or costs 

resulting from the incorrect installation of Haltech prod

-

ucts are totally the responsibility of the installer.
Always  disconnect  the  battery  when  doing  electrical 

work on your vehicle. Avoid sparks, open flames or use 

of electrical devices near flammable substances. Do not 

run the engine with a battery charger connected as this 

could damage the ECU and other electrical equipment. 
Do not overcharge the battery or reverse the polarity of 

the battery or any charging unit. Disconnect the Haltech 

ECU  from  the  electrical  system  whenever  doing  any 

welding on the vehicle by unplugging the wiring harness 

connector from the ECU. 
After completing the ECU installation, make sure there is 

no wiring left un-insulated. Uninsulated wiring can cause 

sparks, short circuits and in some cases fire. Before at

-

tempting to run the engine ensure there are no leaks in 

the fuel system.  
All fuel system components and wiring should be mount

-

ed  away  from  heat  sources,  shielded  if  necessary  and 

well  ventilated.  Always  ensure  that  you  follow  work

-

shop safety procedures. If you’re working underneath a 

jacked-up car, always use safety stands!
