I'm getting ready to install the blocker plate and finger stick in my 2005 LLY Silverado. I want to make sure about the wire connections. If I read the instructions right the only wire on the truck that gets completly cut is the Yellow MAF wire? All other connections are tapped into the truck wires. Tell me if this looks right.

Stick Truck
Power (red) Tap into Blue/white
Ground (grey) Tap into Pink
MAF sensor In (yellow) Butt splice into Yellow on MAF side
Maf sensor Out (Yellow/Green) Butt splice into Yellow left over

I thought there was a DIY post with pictures in it somewhere on here. If i'm thinking right. I know i seen one somewhere, i had to use it. :D

I found the thread, so I think I'm clear now.

Just put the blocker plate, fingerstick and Tx cold air intake on yesterday. To answer your question YES only cut the yellow wire.

So far no check engine light!!

Moving to electrical...
