GVR-4 Wiring ECB-1 with Link

[KCDsmDude]

I picked up the Innovate ECB-1 and wanted to get a few questions out of the way before I started to install. Fair warning, I am an absolute rookie when it comes to wiring but need to learn.

The product is here: https://www.innovatemotorsports.com/products/ecb1.php - instructions are down below in a clickable link.
I also have the ECMlink flex fuel sensor harness here: http://www.ecmtuning.com/product_info.php?manufacturers_id=10&products_id=70

From the instructions for the ECB-1; page 6, I'm mainly concerned with what I do with the yellow and brown wires. I plan on running the red wire, for a 12v source, to the radio harness for a constant source, the ground will be run straight to chassis, and the white will be wired to the cig lighter for on/off illumination of the gauge.

The car currently has Speed Density, but doesn't have a flex fuel sensor at the moment (will be installing). For the two wires listed above, where would I solder those in? Should I be tapping into a current harness for the yellow (wideband) and then where will I wire the brown (ethanol %).

Car also uses the wideband in place of the factory 02 sensor.

Additionally this pink wire was cut when I opened it. Any clue what it goes to?

1) Dont ever let an innovate product share power with anything. Run a dedicated power source with relay from the battery. Full stop.
2) Connect the ground wire to the ecu chassis ground (not sure where that is on 2g) or connect that straight to battery.
3) wideband wire should go to egr or rear o2 pin, Front o2 pin if you want to do narrowband simulation but I highly suggest you not do that. I'd run to rear o2.
4) Brown wire goes to one of maf pins outlined in the ecmlink page. It's not hard to find. Don't connect pink to anything.

Ok. Speaking this into existence

1) Dedicated wire from battery to fuse (What gauge wire is sufficient here?), from fuse (5 amp) to relay (12 volt Bosch/Tyco 30 amp), from relay to Innovate gauge red wire
2) Simple enough
3) I'll need to add in the stock o2 sensor back in and make some adjustments, additionally will need to have a bung welded in 18" from turbo for this wideband
4) Will look this up when I have another free moment.

Thanks for the reply, Vegas

14-16g wire would be fine.
It's worth it to add the front o2 back in because not only is it better at controlling fuel trims, you'll also have a backup o2 sensor in case the wideband goes bad. I've seen it, and experienced it, many times where these widebands lose connection or go bad and the car isn't drivable. Just because people run just one sensor does not mean you should...in my opinion.

Fair enough.

I bought the car this way, and it was tuned and making great power on the current setup. Currently in the process of gathering all the things I need to swap over to a 6466, and replacing the wideband was one of them. Car currently has an AEM Uego and the faceplate of my afr gauge is broken, so I wanted to replace with something nicer.

That car is beauty. Glad I could help.

I did the same thing you did. Bought one after 10 years and now battling the steep learning curve once again .
