⚡ QUICKMECH™ 6-PACK RELAY BYPASS SWITCH KIT — STOP GUESSING. START DIAGNOSING.

Every mechanic knows this scenario. Customer rolls in: "My fuel pump isn't priming." You pop the underhood fuse box, stare at six identical black relays, and now what? Swap one from the wiper circuit and hope? Order a new $40 OEM relay and pray it fixes it? Or actually find the problem in 30 seconds with the right tool.

The QuickMech™ Relay Bypass Switch Kit ends the guessing game.

━━━━━━━━━━━━━━━━━━━━━━━━━━
⚡ HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━

Pull the suspect relay. Drop in the matching QuickMech™ bypass switch (six sizes included — one will fit). Turn the ignition to RUN. Flip the switch to ON. If the circuit works — the relay was bad. If it still doesn't — your relay is fine, and the fault is elsewhere (wiring, ground, fuse, sensor, or the component itself). Total diagnostic time: under one minute. Total parts wasted: zero.

🔌 The Perfect Companion for Every Electrical Diagnosis

Fuel pump won't prime? Power windows dead? Headlights cutting out? Cooling fan not kicking on? Stop swapping relays from your neighbor's car. Drop a QuickMech™ bypass switch into the suspect relay socket, flip ON, and instantly know whether the relay was the problem — or whether you're chasing a wiring fault, a bad ground, or a failed component downstream. Six form factors cover virtually every domestic, Japanese, Korean, and German vehicle from 1985 to today. Whether you're an ASE-certified diagnostic tech or a driveway DIYer, this kit pays for itself the first time you skip a $40 OEM relay you didn't need.
