Hey, if you're working on car wiring with Metri-Pack 150 series connectors, these little wire organizers (they're called TPA – Terminal Position Assurance) are a must-have. They come in a pack of 10, which is perfect because you'll probably need a few for different connectors. They're the cream color, which matches the standard for this series. Their job is super important – they lock the wires into the connector housing to make sure they don't pop out or cause a bad connection. Think of them like a safety latch for your electrical connections. They fit 22 to 16 gauge wires, which covers a lot of common automotive uses. The part number is 12045690, so you can cross-reference it with your needs. They're unsealed type, which is typical for many under-hood applications. Super easy to use – just snap them into the connector after you've inserted the terminals. A super small part that makes a huge difference in reliability. Every auto electrician or serious DIYer should have a bunch of these on hand.
