Wideband O2 Sensor wires / connections??

[RyleyMA61]

Hello

I've got myself a very cheap Haltech wideband (It has Audi and VW symbols on it, so I assume it is the Bosch Type). It has the sensor and controller, with 3 outputs.

Two of which look like a small headphones (RCA Jack?!) inputs, one reads 'input' and the other.... 'output'.

The third wire has been cut. It has 7 smaller wires inside, with the following colours:

Red
Black
Yellow
Brown
Green
Blue
White

Now, I wish to connect this up to a gauge/innovate style system so I can whack it in the exhaust of any car and measure away.

What wires need to be connected to what? I know O2 sensors usually have heater wires and whatnot.

Any help would be great.

Thanks,
Ryley

are you looking at the wirse coming out of the controller? or the sensor?

you wan tto keep using the haltech controller? or use an innovate controller?

sorry, looking at the wires coming from the controller.

i just wish to be able to hook it up to the cheapest and easiest monitoring system... whether it is innovate or a dodgy ebay gauge i a not too fussed!

cheers,'

fwiw: i got a Jaycar kit to display the 0-1v output from my Innovate controller (was the 2nd output, 1st output went to the ECU.

Also - the Haltech item is a re-badged Innovate Wideband sensor/controller.

It will be an LC1 i think - and one of the small headphone connectors goes to an adaptor that turns it into a serial plug. The other wires are power, earths, indicator led & outputs.

Note: follow the instructions about earthing as per the manual - otherwise you will regularly bork the calibration settings in the controller.

Also ensure that your engine to chassis/battery earth is good - rear mounted batteries using the floorpan as an earth are not good for the LC1 unless you've done adequate stitch welding from floor panels to chassis rails


edit: to control/configure the unit, you install LM Programmer - which appears to be part of their LogWorks 3.0 package.

edit 2: assuming the haltech-badged units are configurable with Innovate's software, you can program the range of both outputs (e.g. make the 2nd behave like a narrowband sensor) and you can then use any gauge (within reason) that displays a voltage range.

I found it easier to have the coloured bargraph with stoich in the middle - looking at a numerical reading is distracting.
