Check Engine Light After Spartan2 Lambda Install

[Fenderbass]

Hey guys,

So i just installed a Spartan2 Lambda controller with a wide band oxygen sensor. i thought i followed the instructions, but i have a check engine light now. i'm pretty confidet in my soldering, but maybe i have a wire wrong somewhere???

Here is what i worked with:

OEM:
BK/LB - Sensor Ground
BK/DG - O2 Sensor Signal
BK/TN - Heater ground
DG/OR - IGN Feed

Spartan2:
Red - power
Black - Electronics Ground
White - Heater Ground
Green - Linear output
Brown - Simulated narrowband output

What I Wired:
OEM Sensor ground to Black Spartan
OEM O2 Sensor signal to Brown Spartan
OEM Heater ground to White Spartan
OEM IGN Feed to Red Spartan

Here are some pics if that helps...

Not gonna lie, feeling kinda dumb right now, and i'm sure that i missed something simple.

Yup I’m an idiot. Accidentally disconnected the boost gauge and it threw the check engine light 😑

Good news that it was an easy fix

Ya it was super easy to install. I must have unplugged the vacuum while i was pushing the cables through the firewall.

It's always the simple things lol.
