O2 sensor question and custom ignition setup question
 

Haltech E6X in a 91 TII

1. How do you wire up the 4 wire Haltech O2 sensor? Is it just as the wiring diagram shows? From the main harness it says grey/red to A. Black to B. Shielded Grey to C? Just want to make sure because the diagram states to look in the manual for different wiring configs with different multi-wire O2 sensors and I cannot find the damn reference.

2. I have two Jacobs Pro Street power packs and two Jacobs Ultra coils. One set each for each leading plug. Stock trailing. Any suggestions for wiring these up with the Hatech?

3. Do I need the road speed sensor or can I cut that out?

Found the answer to my 3rd question with A SEARCH :doh:

Still need help with the other two....

Re: O2 sensor question and custom ignition setup question
 

Haltech gray/red = +12VDC switched
Haltech black/white = ground
Haltech shielded = O2 signal

I know 3-wire is:
black = O2 signal
two white = heater circuit (one to +12VDC and other is ground)

I think 4 wire is two white, black, and gray.
But, I dunno what wires do to what - I think the Haltech manual has this?



Install them after the stock ignitor and nothing changes on the Haltech (ignition) settings.
