Anyone have MSD Dis 4?

[Roush21]

For all you guys that have the MSD Dis 4 especially on 96-98 cobras, do you know if you had to use the bypass plug? I want to buy a used one from a guy and he says its off his 98 cobra which is exactly what I have. He says everything is complete and was sent to MSD to have it tested and everything was good but the only thing missing is the bypass plug which he says he didnt need it so he lost it. So i dont really like to buy used parts but it's a pretty good deal to pass up so if you can tell me if i can use this w/o the bypass plug that would be great. thanx

The bypas plug is only used if something happens to the unit.You plug it in and the car will then start..If you dont have it and the MSD fails,your car wont start..If you can get a good deal on it buy it...Btw,make sure it has the 2 tach adapters with it.
