SMC kit, hook up the colored wire to each other, all the wires should match. Then you will have a Red (power) and Black (ground). Just hook those up one to ground, other to an ignition hot (only hot when key is on, radio fuse works well). If you have an AEM, hook a T into the green wire on the set of 4 and it will hook into the nitrous port on the AEM, call Dan Buschur and he can tell you which one that is. As for the snowmeth failsafe, I cant help you there. If you have anymore questions, feel free to PM me as I dont check these parts.
