Thanks for the great video and hopefully this helps for folks where the colors don't completely line up. Use a multimeter and double check but this looks correct. I believe from the diagram at 8:26 , and the colors matched to my 97 compared to the 94 in the video, that the wiring from the oxy sensor plugs perspective with the user facing the plug side with the tab up and clip down. Upper Left : Sensor, Upper Right : Switched Power Lower Left : Sensor Gnd, Lower Right : Heater Gnd.
@@OGPedXing I'll update it when I get my Spartan2 in if it's wrong for some reason. This has been an informative video so I figured I'd give back with what I can.
Absolute long shot if your account is still active but if running an aftermarket ecu with no wideband guage, I’d replace the brown wire with the green?
Haha, yep still here. No videos in a while due to my work situation but I still try to reply to all questions. So, if I understand correctly, you have the spartan 2 but also an aftermarket ecu that doesn't support wideband? Or you mean just the ecu with no wideband guage? For the second situation (no guage) yes, route the green to it and the ecu will get the wb signal and be able to use it. If you can connect a laptop or phone to the ecu then often you can do a digital/virtual gauge. If it's the first situation (maybe a power card setup) then you want to send it the brown wire which is the simulated narrowband signal.
@@OGPedXing you are amazing my friend! And to instantly reply too. Yes it’s the second scenario as you listed, I’m using the Speeduino ecu and I have an early mk1 mx5. So stock is a single wire going from sensor to ecu and this where I was getting so confused as I couldn’t find any guides online of these parts and scenario. But I now know exactly what I need to do to wire it up correctly so hopefully she’ll be purring very soon. Again thank you so much for the quick message, I really really appreciate the video and comment
@nanodisk7914 glad to help. That should work out fine, be sure to configure the input in tuner studio to wideband , I think the spartan will be in the drop down list even. I've played with speeduino a bit (converted a early version of the pnp one for a mk1 to work with my mk2 na (1994)). My main issue was the tune it came with was pretty bad, I had to start from scratch and redo a bunch of things like injector angle, spark timing, and then do the normal fuel ve tuning. I eventually got it running fairly smoothly.
So basically the wide band sensor connects to the controller, then the controller gets wired to the speedhut gauge(the yellow wire)? I’ve watched this like 4 times trying to get it down but am still lost lol. I’m fixing to order me a A/F gauge from speedhut and the controller and wider band from 14point7. Just want to make sure I get the right stuff. Thanks.
Yes, you've got it. The sensor itself has a waterproof plug that connects to the controller. The controller is then wired into power, ground as needed and then the yellow wire goes to the gauge. The AFR gauge from Speedhut has a specific module that's pre-configured for the 14point7 controller. If you have an aftermarket ECU that also needs the wideband signal, you can split the yellow wire to both your gauge and your ECU with no trouble.
I got an afr and boost from speedhut.com. Good quality and you can pick the font, colors, needle style, tickmarks, it's awesome. The afr is pretuned for the controller you want (aem, innovate, or Spartan 2)
For the Spartan 2 the brown is a dedicated narrowband and the green is the wide band signal. So for an aftermarket ECU you'll need to split the green to go to both the gauge and the ECU. Splitting the signal is no problem, I confirmed with the manufacturer to be sure.
@@OGPedXing legend! Thankyou! Still running ok with your setup? I've been told to find 12v at the fuel pump and grounds at the ecu instead of using the grounds from the 4 wire. Your way seems easier
@@shirtz69r yep, no problems. When I did it originally I was using the narrowband output with the stock ECU. When I went to a megasquirt, I left that exactly the same and just split out the wideband output (green) from the gauge to the megasquirt WB input. It was handy because I could put the stock ECU back in to troubleshoot and it would still work.
@@shirtz69r oh also, the sensor ground at the 4 wire plug is the sensor ground for the ECU. So no differences between what the gauge shows and what the ECU gets.

Awesome, thanks for the info

Hey dude do you have it installed in the car yet? Does yours make a quiet but clearly audible high pitched ringing noise?

Where did you find that classic style AFR gauge? One like that would go perfect with my other classic style smiths gauges.

I have a video actually,
th-cam.com/video/ADz_CSqSO7M/w-d-xo.html and
th-cam.com/video/LBlpVV7_4KM/w-d-xo.html
So brown to blue on 02 and green to yellow on the guage. Does this change when u have an aftermarket ecu?

@@OGPedXing thank you kind sir. Will put it in and report back
*installed in the car with a standalone like ms2 or something.
Yes I've got it with an ms3x (check out my build series)...I can't hear anything from it. Seems normal.
