I got this diagram from the sticky above, I didnt want to post a reply in it. but I have a q about the diagram. I just would like to make the way I have this wired is correctly.

Also I'd like to know if I need to have the O2 hooked up from the wiring on the haltech or can I just have my own widband hooked up outside the ECU. Is the factory water temp sensor sufficient or do i need to use the sensor from haltech

 

Anyone?

How about the injectors signal does it use high or low impedance?

 

The diagram appears correct but it's very fuzzy and hard to tell.

You do not need the O2 sensor.

Injector impedance setting depends on the actual injector impedance. What is the ohm reading across the injectors?

The stock water temp sensor will work but it won't be absolutely accurate. There is a replacement sensor offered that is a direct swap for the stock sensor. No need to drill and tap the housing.

 

Primaries are high and the secondaries are low. If it is selectable in the ECU thats great if not I have the resistors. Yeah, the diagram was kinda fuzy but i couldnt make it any better. I just wanted to make sure it was right before I had any attempt at starting. I think thats what I may do get the haltech sensor. Thanks for that one too btw..

 

anything on the injectors..sry ive been away for a few weeks..
