ie been searching a a while and cant find anything concrete i want to get a msd box to retard timing but would like to know how to set it up before i get it i would be installing it on a 91 miata can anyone help.

 

It wires into your cas sensor. All the wires just tag in. But one wire you have to cut and attachthe in and out wires of the msd box. Then you have a vaccum line to hook up.

Dragging butt and checking out hott chicks, at the same time. I can wire one in, in about 7mins.

It is easy.
