Haltech 34 Pin Keyway Superseal Connector

Haltech 34 Pin Superseal Connector, Key 1

This is the 34 pin Superseal plug used across a big chunk of the Haltech lineup, and it's one of those parts that's frustrating to find when you need it. Building a harness from scratch, repairing a damaged plug, or adding a second ECU to a project, this is the correct connector with the pins to go with it.

Check Your Keyway: This Is Key 1

Important before you order. Superseal connectors of the same pin count come in different keyways so they can't be plugged into the wrong port, and this is the Key 1 version. A different key won't mate, no matter how identical the connectors look side by side. If your ECU or dash uses a different keyway, you need that version instead, so confirm which one you're replacing before you buy.

What It Fits

This one covers a lot of ground across the Haltech range:

• Nexus PD16
• Elite 550, 750, and 950 ECUs
• Haltech IQ3 Street Dashes
• The large connector on Nexus R5, Elite 1000 through 2500, PS1000, PS2000, and E8/E11 ECUs

That breadth is worth noting. If you're running more than one Haltech product in a build, there's a good chance this same connector serves several of them.

Why Superseal

Superseal connectors are built for exactly the environment an engine bay creates. They seal against moisture and dirt at both the mating face and the wire entry, they handle vibration without backing out, and they lock positively rather than depending on friction. On a harness carrying ECU signals, a connector that lets water in or works loose is how you end up chasing an intermittent fault that only appears when it rains.

What's Included

You get the 34 pin plug and the pins. It's plug and pins only, so you'll want the correct crimper for these terminals rather than trying to solder or crimp them with generic tooling. Doing it properly is the difference between a harness that lasts and one you revisit.
