As mentioned above, if you want test leads with CB specific connectors on them it would be simple enough to make them yourself. The time and expense of doing so would really not be worth it unless you are rebuilding a lot of bikes. Test probes and alligator clips should be sufficient for general electrical troubleshooting. I work as an electrical technician for a major metropolitan utility. 95+% of the time that is what we use for troubleshooting circuits with a multimeter. Anything more specific we will fabricate.
For example, you could make up some short jumpers with male and female bullet connectors on one end and clips on the other to plug into the harness and clip to your test leads. I don’t think you will find such an item available commercially.
