Uscar→住友 アダプター、50個入りケース

Finally a proper solution for swapping injector connectors without hacking up the harness. The case of 50 means I've got plenty for multiple jobs, and the pin fitment is spot-on with no wiggle.

The click when these snap into place is so satisfying—they fit both Uscar and Sumitomo ports perfectly. I've already used about 15 on various injectors without a single loose connection. This case will definitely save me time on future builds.

Used these to swap out the old injector connectors on my project car, and the plug-and-play fit was spot-on for both sides. Having a case of 50 means I won't run out mid-job, and the wiring harness side clicks in with a satisfying snap every time.
