[V8] Radio Antenna Connectors

[Gunter]

Another question while I'm on a roll..........

Does anyone know how to quickly differentiate between the two antenna leads that feed into the radio...............I found two male prong antenna connector cables (at least that's how they look to me) but one is smaller than the other and does not look like other universal connectors I've seen.............I'm going to assume that the smaller one is for the rear window..............but someone else might know otherwise???  I've played around with my circuit tester but no luck in clarifying this for myself.........


Thanks,
