This is the center engine information or DIC LCD found in the 1985 to 1989 Corvette Digital dash cluster. It will NOT work in the 1984 cluster, please see my other listing of that part. The auction is for the LCD part only NOT THE ENTIRE CLUSTER. The pictures show the LCD in test mode and the actual part as shipped. Detailed installation instructions are included. No special tools are needed but it's recomended that you have very good mechanical ability. There are three LCDs in the 84-89 C4 Corvette Digital dash cluster: speed, center, and tach. See my other listing for these parts as well as xenon illumination bulbs. Satisfaction guaranteed or full refund, provided part is returned in new condition. Shipping is free in US, $25 worldwide. I also offer a flat rate rebuild service for $375 please email for info.
