Procede install immediate CELs

Power is good, ground is good, wiring is good, installed with battery disconnected, followed the video(3 times now)

I am getting a brake light CEL and the reduced power CEL. I have no idea and i'm a bit upset with the whole situation.

Please help!

unplug everything and get it back to stock. if you have no problems then you know you took a wrong turn somewhere in the installation. if the problem persists then you didn't plug one of the harnesses back correctly.

try this.

First try putting the bypass connector plugs in (without taking harnes out) if it throws a CEL still, then it is your wiring.... if not.. then it might be your car doesnt like that map....

Double check everything and make sure its good...

i think i may have identified the problem...my connector for the vacuum lines has only been slid fully into palce on 1 side the other side is about 90% of the way to the stoppers might this have caused the CEL?

no such luck still getting the CEL and it is acting really strange at idle...like it shudders almost as if it is going to stall and then sits at idle for a sec and does it again.

Interesting. I realize there is a mention on the Vishnu website that says to disconnect the battery, but that's not a step in the video or in the written instructions. I didn't disconnect the battery and haven't had any issues whatsoever. Install went smooth as glass...

Just that wires aren't broken anywhere and the end connectors are also on right.

as much as i can visually i went through what i got thoroughly and installed it and hour later and was very careful with the wires as I have a tendency to try and force things that should be finessed
