This article features pump diagrams for wiring in your water methanol pump, including both high-side (recommended) and low-side wiring configurations. Follow these recommended diagrams to ensure proper control and reliable performance, allowing you to choose the setup that best fits your application.
High Side Method (Recommended)
Products:
- Solid State Relay (SSR) DC/DC Style
- Flyback Diode
- Inline Fuse
- 1K - Sealed Resistor
High Side Method Wiring:
- Pin 1 - Supplies Power to Pump
- Pin 2 - 12V Battery Power to SSR
- Pin 3 - 12V Switched Power to SSR
-
Pin 4 - ECU Output to SSR
- PWM Out - Ground Trigger (Recommended)
- Hi-Current – Ground Trigger
- Injector – Ground Trigger
-
Flyback Diode
- This needs to be installed across the (+) and (-) of the pump
- Banded-side to 12V
- Recommended installed at the pump
-
Pull-up Resistor
- This is installed between Pin 3 and Pin 4 on the SSR
Low Side Method
Products:
- Solid State Relay (SSR) DC/DC Style
- Flyback Diode
- Inline Fuse
- 1K - Sealed Resistor
Low Side Method Wiring:
- Pin 1 - Ground to SSR
- Pin 2 - Supplies Ground to Pump
- Pin 3 - 12V Switched Power to SSR
-
Pin 4 - ECU Output to SSR
- PWM Out - Ground Trigger (Recommended)
- Hi-Current – Ground Trigger
- Injector – Ground Trigger
-
Flyback Diode
- This needs to be installed across the (+) and (-) of the pump
- Banded-side to 12V
- Recommended close to the pump
-
Pull-up Resistor
- This is installed between Pin 3 and Pin 4 on the SSR
