Ok, so I got an SR5 guage cluster from an 86 to go into my 86. I currently have the bare bones cluster with just the speedo and idiot lights..... I have a chiltons manual but the schematic it gives me is a "typical" schematic for "late model"..... whatever that means. Before I go out and spend $$$ on the factory service manual has anyone done the swap?? If so what recommendations do you have..
