What This Harness Does
When swapping between Honda K20 and Honda K24, crank sensor connectors may differ depending on engine year and ECU combination.
This conversion harness:
-
Adapts K20 sensor wiring to K24 configuration (or vice versa depending on version)
-
Maintains proper signal integrity
-
Preserves factory-style fitment
-
Eliminates wire splicing
It’s the clean solution for hybrid K builds.
Key Features
-
True plug-and-play design
-
High-flex automotive-grade wiring
-
OEM-style connectors
-
Secure locking tabs
-
Heat-resistant insulation
-
Designed for K-series engine swaps
Translation: installs in minutes. Works for years.

Why It Matters
The crankshaft position sensor controls:
-
Ignition timing
-
Fuel injection timing
-
Engine synchronization
Incorrect wiring can cause:
-
No-start conditions
-
Misfires
-
Check engine lights
-
Erratic idle
On a swapped or hybrid motor, the right connector saves headaches.
Ideal Applications
-
K24 bottom end with K20 head builds
-
ECU conversions
-
Engine harness swaps
-
K-swapped Civic / RSX projects
Especially useful in custom K-swap setups where harness compatibility varies.
Installation Notes
-
Confirm sensor type before ordering
-
Inspect pins for damage before connecting
-
Secure away from heat sources
-
Clear codes after installation
Because troubleshooting wiring after the motor’s in is not fun.
Final Verdict
The K20 to K24 Crankshaft Sensor Conversion Harness is a simple but critical component for hybrid K-series builds. Clean install, correct signal transfer, and no sketchy splicing.
Because a no-start issue after a fresh swap hits different.

I used this in order to start my k24a with a usdm RSX-style swap harness. Didn’t wanna buy a new sensor, and this was a similar price. Can’t speak for longevity, but again, the car started.
