I bought a used msd boost a pump and it did'nt come with any instructions. I could probalby figure it out but it would go a lot faster if somebody could tell me how theres is hooked up. I realize the 10-12 gauge red and black go to groud and power. I also know a vaccum line goes on it. Now on the other side is where I could use a little help. I have a orange wire running to the relay and off the relay a small gauge red and black, where do they go? On that same side there is another large ground wire. Also could you tell me how to adjust the voltage.
