My brake lights come on randomly?

My manual shows where it is & tells how to replace it. The problem is, I can't reach where it is supposed to be. So, once again, Can someone help me access it without me having to remove my dashboard? By looking at the diagrams, it appears to be behind my tachometer.

Maybe mine is different than others, but is actually inside my dash. As I said I can't reach it by going under. It is basically above/ next to steering column. Once I could see it, I removed & installed new one using tools, since I can't reach it. Removed the bottom half of driver's side dash. Driving & working on this truck I have found that a lot is different than similar vehicles. You would not believe the hassle to get parts because most computer systems don't list that year as coming with fuel injection, I have to take the people to my truck & pop the hood to prove it, then get sent away because they can't help. I learned recently to carry my vin with me for look ups, works about 50% of time.
