SPDZ1 Budget D-series and B-series compatible wire-tuck engine harness is nearly identical to our Mil-spec engine harness line with the primary difference being, the single black wire color and expandable loom used. There are quite a few options available. Please look through them carefully to make sure you get the right parts! 

All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Our engine harnesses are 100% quality tested pin to pin; And resistance checked to ensure no voltage fluctuations.


-All SPDZ1 engine harnesses are made with OBD1 (92-95) ECU Connectors.

-An ECU adapter must be used for OBD2a or OBD2b ECU's if necessary.

-Our harness does not support USDM OBD2 ECU's.

Aftermarket ECU's using OBD2 plugs & Non-US OBD2 ECUs are compatible! (except for H22 and GSR stock computers).


These harnesses are warrantied and guaranteed to work, however they are non-refundable. Because the back-side (interior/shock tower connection) separates from the main harness, the engine harness can be used on multiple chassis provided the engine itself uses the same components. We sell the back-side harness separately only over the phone for previous engine harness customers.
