4E-FTE Distributor Pinout Diagram (24 Tooth & Cam Sync)
When wiring a standalone ECU to use the stock 4E-FTE distributor/cam sensor you can use the following pinout for the connector. For 99% of people the cam sensor wired this way is perfectly acceptable way to run the car, even for big power goals!
| Connector Pin | Link ECU Connection | Description |
|---|---|---|
| 1 | Link ECU Connector A – Pin 8 | Trig 1 – 24 Tooth (NE) |
| 2 | N.C. (Not connected) | (G1) |
| 3 | Link ECU Connector A – Pin 9 | Trig 2 – Cam Sync (G2) |
| 4 | Link ECU Connector A – Pin 7 | Shield / Sensor Ground (G-) |
4E-FTE Distributor Pinout Diagram (Cam Sync only – Additional Crank Trigger)
If you are running a crank sensor with missing teeth along with the cam/distributor sensor, you can use pins 3 and 4 as the Cam Sync in order to run sequential ignition/injection.
| Connector Pin | Link ECU Connection | Description |
|---|---|---|
| 1 | N.C. (Not connected) | (NE) |
| 2 | N.C. (Not connected) | (G1) |
| 3 | Link ECU Connector A – Pin 9 | Trig 2 – Cam Sync (G2) |
| 4 | Link ECU Connector A – Pin 7 | Shield / Sensor Ground (G-) |

4E-FTE Distributor Link ECU Settings
| Link ECU Setting | Value |
|---|---|
| Trigger Mode | Multi-Tooth |
| Trigger Type (Trigger 1 & 2) | Reluctor |
| Trigger Filtering (Trigger 1 & 2) | Level 1 (Low) |
| Trigger 1 – Multi-Tooth Position | Cam (if using 4E-FTE Dist/Cam for Trig 1 & 2) |
| Trigger 1 – Tooth Count | 24 |
| Trigger 1 – Sync Tooth | 1 |
| Trigger 2 – Sync Mode | Cam Pulse 1x |
4E-FTE Stock Ignition Coil & Ignitor
The stock coil is capable of a lot of power so if it’s in good working order then there is really no reason to replace it.
4E-FTE Ignitor (Ignition Module) Pinout Diagram
| Pin | Link ECU Connection | Description |
|---|---|---|
| 1 | N.C. (Not connected) | Ignition Feedback – Not required for standalone ECU (IGF) |
| 2 | Link ECU Connector A – Pin 13 | Ignition Signal from ECU (IGT) |
| 3 | – | Ignition switched 12V+ Power (15amp AM2 fuse) (B+) |
| 4 | – | High side output to drive tachometer (TACH) |
| 5 | (see below) | Goes to Ignition Coil – Pin 2 (C-) |

Honda K20 Ignition Coil
This connector accepts 3 wires – Ignition Signal, Ground & 12V+ Power. The pinout and dwell information can also be found on the Haltech Website Here
| Pin | Description |
|---|---|
| 1 | ECU Ignition Output/Signal |
| 2 | Ground to Cylinder Head |
| 3 | Ignition switched 12V+ Power (15amp AM2 fuse) |
Pins 1, 2 and 3 – Looking into the front of the connector from Left to Right. Pin 1 closest to the release clip.
Honda K20 Ignition Coil – ECU Config & Dwell Table
K20 coils are smart coils where the ignitor is inside of the coil itself. In Link ECU the Spark Edge should be set to Falling edge. Selecting incorrect settings will damage the coil and possibly the ECU.
