HELP ASAP! Electrical Problems

yeah im pretty sure its got to be the IVR. The dimming is nothing new, but it did seem more intense than normal. I do have a spare guage cluster so i will swap that out tomorrow. How safe is it to drive? right now it is my daily driver but i took out my motorcycle today to make sure not to screw anything else up.
Sure throw a used one in there and experience a different fault condition. No such thing as a good used one. ORiellys auto parts can sell you a new one for 18 bucks (only source today) made by Borg using same 50 year old technology.
