UPDATE 20251212Updated v2.1. Made the clipping ears less pronged to damage from repeat install/uninstallSmall version fits ~22mm plastic retaining ring (It fits OEM and some cheap Amazon special I tried)Big version fits ~24.3mm plastic retaining ring (It fits some aftermarket one that came with my car, maybe the automatic variant, not sure) Background:Previous owner of my 92 Miata broke the alternator cap on the positive wire, so created this.This simply goes over the connection unlike the original one having to clip on the wire and have a cap where the joint breaks easily.Originally thought about print it with TPU to achieve tight fitment but went with ASA due to it being in the engine bay.
