- Connect Coil 1,2,3 and 4 to the drive signals to each coil packs as necessary.
- We recommend 24 gauge wire, but wire gauge is not critical- so long as it fits the module.
- Connect the tach output to the input of your tachometer.
- Seal the module with shrink tubing or electrical tape- the board is small enough to integrate into your wire harness / bundle.
Example wiring for a 4 cylinder wasted spark application: yellow wire connects to Tachometer input; red and black wire connect to the drive signals for the coil packs.
