Is it possible to hook a retard control [8770] into my already working 7-al2 and 2-step ignition. If possible, could you furnish a wiring diagram of this?

Default upon further review, 8770 intall

Hate to be a pain,but how does 2-step wire into setup? Car really hauls butt & would hate to screw up now. 2-step is now wired to trans. break & works great.

Default Autotronics/msd 8760

Hello, I just bought a altered and it has an old 8760 retard control box on it, I am a little confused as to what it is for. I also would like to know how to wire it as it is unhooked. Any help would be appreciated. Thanks!
