So I have a 2000 blazer 4x4. I dont have the gauge cluster with the RPM gauge. Would it be a direct swap if I found one with the RPM to the left of the MPH? I hate not knowing what RPM I am at when I am giving demos of the system. I dotn want to run wire and add an aftermarket one just want the simplicity to know I am above idle and not at 4000+ lol
