Haltech HT-030013 Nexus R3 Plug and Pin Set AMP 34 Pin Key 1 Key 2 DTP-4 Kit

Vehicle Fitment

• Designed specifically for the Haltech Nexus R3 VCU (Vehicle Control Unit) - includes all three connector plug and pin sets required to construct a complete harness
• Universal - suits any vehicle or application using the Haltech Nexus R3 ECU where a custom wiring harness is being built or an existing harness is being re-pinned

Fitment Notes

• This kit includes all three connectors used on the Nexus R3 - the AMP 34-pin Key 1, AMP 34-pin Key 2, and Deutsch DTP-4. All three must be used to fully terminate a Nexus R3 harness; individual connectors cannot be substituted from other keyway kits without confirming compatibility.
• This is the plug and pin set only - the Nexus R3 ECU is sold separately. This kit suits builders who already own the ECU and need connectors, or who are re-pinning an existing harness for use with the Nexus R3.
• Pins are crimp-style - use appropriate crimp tooling compatible with Haltech AMP Superseal and Deutsch DTP terminals. Refer to the Nexus R3 wiring diagram for correct wire gauge and pin assignments per connector.
• Not interchangeable with plug and pin sets for other Haltech ECUs - the Nexus R3 uses a specific 3-connector combination (Key 1 + Key 2 + DTP-4) not shared by all other Nexus models.

Features

• Complete 3-connector plug and pin set for a full Nexus R3 harness build - includes Key 1, Key 2, and DTP-4 connectors in one kit.
• AMP/Tyco Superseal 34-pin Key 1 connector covers the first 34-pin header on the Nexus R3.
• AMP/Tyco Superseal 34-pin Key 2 connector covers the second 34-pin header on the Nexus R3.
• Deutsch DTP-4 position connector covers the power/ground 4-pin header on the Nexus R3.
• Weather-resistant Superseal and Deutsch connector designs provide sealed, moisture-resistant connections appropriate for engine bay wiring.
• All pins and wedge locks included - no additional hardware required for a complete harness termination.
• The all-in-one kit eliminates the need to source three separate connector sets, reducing build complexity and parts ordering time.

Product Description

The Haltech HT-030013 is the complete plug and pin set for the Nexus R3 VCU, providing all three connectors required to fully terminate a custom wiring harness. The Nexus R3 uses two AMP Superseal 34-pin connectors (Key 1 and Key 2) plus a Deutsch DTP-4 power connector - this kit includes all three with their respective pins and wedge locks, saving the harness builder from sourcing each connector separately. It is the recommended choice for builders constructing a new harness from scratch or re-pinning an existing harness for a Nexus R3 installation.

The Nexus R3 ECU is sold separately - this kit is plug and pins only. All pins are crimp-style and require appropriate crimp tooling. Refer to the Haltech Nexus R3 wiring diagram for pin assignments, wire gauge specifications, and connector orientation before termination. This connector set is specific to the Nexus R3; other Nexus models (R5, S3, S2) use different connector combinations and are not interchangeable with this kit.
