Another new ZR1 owner!...but need help with black box

[coltmckinney]

Hi fellow King owners. I just bought a heavily modified 1990 ZR1 and can't belive the power! I thought my 1966 big block was the fastest vette I'd ever drive...Anyway, I have 4.11 gears and need to know how to install the black box that adjusts the speedo accordingly. I don't even know where it goes..thanks

Someone will be along to answer your question but I just wanted to say, hello, and welcome to the forum.

While you do have some nice mods, I wouldn't say you are heavily modified unless you have more done than in your signature. However, I'm sure your baby screams when prompted. Glad to have you aboard.
