What kind of alternator are you using? I have a CS-130/CS-144 style alternator in my Bowtie powered CJ-7. The engine is a 2000 Vortec with 1991 TBI junkyard injection I robbed off my Suburban that was parted out for Jeep parts. It is super easy to wire up and even easier to fool into upping the system voltage so your accessories run better.
On my Jeep the wire I used on the GM starter was the original one that went to the fender mounted Ford style solenoid. I took the second terminal that bypassed/removed the resistor wire out because GM uses straight 12V to power the coil on HEI ignition systems.
If you have a factory wiring diagram for your CJ-7, the exact wire number is # 13F, it comes out of the firewall and is one of the two wires that powered the DuraSpark Ford ignition module. That is the 12V from the ignition side of the key and will work for your Distributor.
Use wire # 14A (light Blue) from the firewall that originally went to the solenoid terminal on the left side (ignition "Crank" Hot side), to your small terminal on the GM starter. This will engage your solenoid when you turn the key to "Start".
Use wire from terminal 78 on the Alternator. This has a short piece of Nichrome resistance wire in it and will work to power 10 & 12 SI alternators as is with no modification. If you are using a CS-130 or CS-140 Like I do, use this wire and tie it to the "L" terminal on the regulator. Tie the Battery terminal to the "S" terminal if used on the regulator plug. If you want to put a "Charge" lamp in, use pin "F" as the ground side of the lamp and the hot side goes to the ignition.
This ought get you running with no issues.
