I just got my diss in thanks to you guys.bought a crt performance diss.no information on wireing it up.it shows some but not all.my questions are do you put the wires from old coil on with the new wires.so you would have two wires on each post.also one wire from ignition to coil and other wire to 12 volts.I am assuming they mean negative post on battery. I have two wires coming out of wireing harness on fire wall.they are in a plug shaped like a vee.is this the ignition wire.do you have to cut these wires.do you run one to plus side of coil.where does the other wire go.

 

Don't cut the wires with the connector until you establish what they are. It could be the backup lights or something else.
CRT appears to be a small outfit offering both the large cap HEI and a small cap. So, to answer your question, which do you have? Pictures would be helpful.
I don't know anything about a CRT distributor, but assume it is like a stock setup for wiring from their install instructions. This might help:

I am thinking 67 and 66 are the same, The original wiring for the point distributor has a pink wire from the ignition switch to the ballast resistor, then another pink wire from the ballast resistor to the positive (+) post of the original coil. There is also an additional pink wire which comes from the starter solenoid "R" terminal to the original coil positive (+) terminal which is not needed for a HEI distributor.
The pink wire coming out of the firewall from the ignition switch to the ballast resistor will go to the HEI terminal marked "coil +". You can splice the wire to the wire of the pigtail for the HEI or you can use the ballast resistor as a splice location if your HEI pigtail wire is long enough to terminate it there.
NOTE: it is recommended you use the IGN terminal in the fuse box and run a new 12 ga. wire to the HEI "coil+" pigtail wire. The 66 does not have a "IGN" terminal powered from the ignition switch, I don't know about a 67.

The large HEI with the coil in the cap requires a ground, thus run a black 12ga wire from the pigtail to the engine block or other good ground.

The HEI may or may not have a tachometer gear drive. Thus, if you are converting to an electronic tach, you will need to connect the trigger wire for the tackometer at the HEI pigtail "TACH"

Don't forget to either disconnect or insulated the pink wire from the starter "R" terminal to the "coil +" as you no longer need it. You could disconnect it at the coil and insulated it in case you want to return to points at some time.

 

I think the distributor is like other hei .it’s a tack drive distributor.it came with two leads to the coil.from the distributor.the coil is not on distributor.its separate from the distributor.all I want to know is do I use the two wires that were on my old coil.along with the two new wires .also I had a ballast what do you do with those wires.because that will break the circuit.
