TachAdapter

Tachometer Adapter

This small board adapts a Tachometer to up to 4 individual coil packs, capable of handling 4, 6 or 8 cylinder wasted spark applications.

Installation

Installation is straightforward:

• Connect Coil 1,2,3 and 4 to the drive signals to each coil packs as necessary.
• Connect the tach output to the input of your tachometer.
• Wrap the board with electrical tape or shrink tubing- the board is small enough to integrate into your wire harness / bundle.

Example Wiring

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.
