I have just installed a Haltech E6K in my TII, everything works fine except one thing, the coolant temp gauge. After some research under the hood I discovered that there was no wire going to the coolant temp sensor. I must have removed it once I installed the haltech! Now to the question, Where goes the wire from the sensor and what shall I do to make the gauge work? Please tell me how you have done with your installation on the TII...

 

You don't need to unhook the temp sender for the gauge when installing a haltech. Just find the wire you unhooked and plug it back in.

 

Ok, but I have checked and didn`t find any wire. Where does it come from, passenger or the drivers-side?

 

I want to say it comes from the pass side and is attached to the main ECU harness. Mine stopped working because I pulled the main ECU harness which had the sensor attached to it as well as my wipers

 

I got the same problem, does anyone know the color of the factory wire that goes to the Radiator temp sensor?

 

I have solved the porblem now, I installed a new wire all the way from the temp-gauge to the sensor. The color of the wire is yellow/white.

 

Thank you for posting the fix!!
