Hey guys, so I was trying to install modifry's redline shift beeper. I am done and I am pretty sure I tapped the wires good, but there is just no beeping, whether it's test mode or actual mode. I only tapped the 12 volt wire, ground wire, and the tach wire. pictures of the setup are below. Please take a look and help me debug.

thanks!

nvm guys i tapped the wrong blue wire. the tach wire is suppose to be a dark blue wire with no stripes but with silver rings. i tapped a light blue wire.
