RB / KA Trigger System Interface Harness

Plug-and-Play Trigger Interface Harness

Simplify the wiring for your TripasGarage crank trigger and cam system with our purpose-built interface harness. (works with other brand trigger kits)

This harness connects the factory engine-side CAS wiring to the two 3-pin DTM connectors used by the TripasGarage crank and home/sync sensors, eliminating the need to build your own wiring or splice into the factory harness.

The harness is available in three configurations to accommodate different factory wiring:

• 4-Pin Version — Compatible with Nissan NON-Neo RB20, RB25, RB26 and S13 KA24DE
• 4-Pin Version — Compatible with Nissan NEO RB20 and RB25
• 6-Pin Version — Compatible with Nissan S14 KA24DE

All versions split into two 3-pin DTM connectors, providing separate connections for the two trigger sensors.

Signal 1 & Signal 2

The two DTM connectors are labeled Signal 1 and Signal 2 rather than “Crank” and “Home.”

This is intentional. Different aftermarket ECU manufacturers may assign the primary trigger and home/sync inputs differently.

Refer to your ECU’s trigger configuration to determine which input should receive the primary trigger signal and which should receive the home/sync signal, then connect Signal 1 and Signal 2 accordingly.

If you are not receiving an RPM signal after installation, verify your ECU’s trigger configuration and wiring. If everything is configured correctly, try swapping  the crank sensor plug to into Signal 2 rather than Signal 1.
