Man, I hate those kind of electrical probs: You do some work, and all of a sudden, theres a new prob
I have the same MSD in my 71 Cuda: I can only say as far as the lights went out, then back on on your fuel and temp face, I dont believe the issue is related with your MSD installation.
There is a light bulb that inserts into the back of the dash cluster that houses your fuel, temp, oil pressure and amp gauge. You might just have a bad bulb to socket connection, maybe slightly corroded, causing an intermittent operation. That bulb/socket is a PIA to get to. You MIGHT be able to reach behind the dash, (I dont recommend this even if you could reach back there. You could unintentionally pull off some wires back there), and pull it out, but if you cant, the whole dash instrument panel needs to come out: Not a tough job, but a little time consuming. The only saving grace here is if you have to remove the dash, you can take the op to also clean/polish the clear plastic, maybe redo the faux woodgrain paneling, etc : A word of advice: If you go this route and remove the dash cluster, TAKE YOUR TIME.
Lower the steering column by removing the four bolts that house the column fasica cover under the dash. Then use a deep socket and loosen ,almost all the way, but do NOT remove, the two nuts (one on each side) that holds the steering column up. As you loosen the nuts, you will see the column start to slowly lower: It will give you enough room to remove the dash without scratching the hell out of the steering column. Its also almost impossible to remove the dash without the extra room as well
Make note of what screws went where. There will be about 20 or so screws total. Be aware, some are hard to see, some are recessed. Some are on the far left (facing the inner door when closed) and far right of the dash, seeming to not even relate to removing the dash: Take your time, and don't force anything. Have a small flashlite to look in the recessed holes or dark areas. You will need a stubby phillips screw driver to get to some of the screws
When you remove the dash, take care of the far left panel that houses the dimmer, wiper and drive light switches. If you pull the switch connectors off the back, understand they are 40 or so years old, and can crack or break very easily: I would NOT use an electric screwdriver, ESPECIALLY when reinstalling. All the dash plastic is very brittle
When you are done inspecting, put the gauge cluster back in place, but before you screw it in or go any further, be sure everything works. BE VERY careful of the amp meter lugs on the back of the dash cluster: Its 12v hot, so you dont want to accidentally ground it.
