my innovate SCG-1 install

[Racin2redline]

I had some interest on my innovate gauge install into my Allroad, I know it sounds simple being its just a wideband gauge, but it can be a little overwhelming considering the amount of wires for 1 gauge.
hopefully to help a few people here's a general rundown of what I did.


my install already had a head start because I had my blockhead and podi digital already installed.
I started by getting back to square one and removing all the wiring for that.
the innovate gauge has a lot more wires and they are all heavier gauge, so I needed to make a bigger hole in the vent, the 1/8in hole wasn't going to cut it
I enlarged the hole with a stepped reaming bit, it worked pretty good without exploding the plastic ducting

(hard to see but you get the idea)

next I found a good location(actually perfect ) for the relay and fuse

at least on my auto-manual swapped allroad there were these existing relays and little fuse holder , with 2 blank locations.
I had a few parts cars at my disposal, so I dug under until I found a female relay block to click up there with a fuse holder with only 4 wires going into it,

I'm sure you can probably buy this and put your own wires that aren't random colors into it and do it super clean, but this will work fine.
the innovate manual explains how to wire a relay so I won't get into that.

I tapped 75x(ignition) and terminal 30(battery) for power and connected the appropriate wires to the relay and fuse
the red scribbled on relay and yellow fuse are the new additions for the gauge

from the engine bay I ran all the wires through the ECU box under the false firewall, including the previously ran map solenoid for the gauge.

I already had all the boost hosing done from the previous install , as you see in the corner I have an inline filter before the map.
I highly recommend that so you dont ruin the sensor.
the wires for the wideband and boost run out into the engine over here

then down and across to the passenger side where I ziptied the new wideband wire to the rear o2 wire.
the green single wire pictured is the signal wire for logging wideband values through the rear o2 sensor. I completely removed the rear o2 and plugged the hole. I put a single spade into the connector and taped it up to the harness.
I'll update this more later
