I took my car to a shop to see why my VTEC isn't popping and they told me the it could be my speedo wire sense speedo doesn't work... could this be true?

whoa, hold on. I dont see why you need to take out your dash.
The Speed Sensor(VSS) is located toward the rear of your transmission. If its a VSS issue causing vtec to not hit it would be here. not under your dash.
