I was in the process of installing my msd 6a box tonight when I realized I was not sure what to spilce the power lead into. Which wire does everyone splice into? The car is a 68 mustang. Thanks in advance everyone.

the power lead as in the big fat positive red wire? I hooked it directly up to the battery terminal. when the msd 6a gets juice from your ignition, thats when it starts taking juice from the big fat positive red wire....

The heavy gauge black to a GOOD chassis ground. Heavy gauge red to the battery side of the starter solenoid. If you are using points, the light gauge red wire goes to the original + coil wire ( red w/ green stripe?). The white wire goes to the black lead coming from the distributor (original coil - wire). The orange goes to coil +, black to coil -. If you want a diagram, go to
