This is the proper Molex/Waldom crimper for the Molex .093 terminals in the 4-pin connectors on this page as well as the Door Speaker Harness Plug - both on this page.
Not for insulated or non-insulated barrel terminals & disconnects - that crimper is our catalog Molex64016. Works with 14-24g wire and will crimp most F-Type terminals. Includes a wire stripper.

Molex Service-Grade Insulated Terminal Crimper
Genuine Molex brand insulated terminal crimper and wire stripper. Crimps Red (22-18g), Blue (16-14g), and Yellow (12-10g) insulated terminals. Also includes a nice wire stripper. Note that this is not the crimper for the Molex 4-pin plugs for under the seats or the NB windblocker that we also sell. That crimper is our catalog Molex1919. This crimper will work for the push on terminals for our speakers and other normal, insulated terminals.
Much better quality than the junk at the local dollar store.
