So you pulled from all four coils?

I only pulled from one, but we'll see when we test the output.

One will do you no good unless you multiply the signal by 4. Been done. When I first did aux I used a tach adapter from split second. Gave a dirty signal so I removed it and used one tap. RPM was 1/4 of value. Ended up building cable with all four taps, issue gone

Guy's make sure you use the 1n4148 or 1n4448 diodes. They are a high speed switching diode. And go no more than a 100 ohm on the resistor to ground. You can get away with not grounding the signal but it does make a good filter.

I am going to assume to use both diodes inline with the signal wire to the device from the coils?

You pull a wire from each coil. Each wire has a single diode on the end with the line (cathode or negative) facing away from the coil. You put all four diode ends together and run a wire from them to the device.

Well this was good timing, saves me a few bucks on not having to buy the tach adapter for the split second! Thanks!! What capacity would the 100 ohm resistor need?

1/4 watt. Yes this works great with the SS. I had the adapter and it doesn't work very well.

If you really want to get fancy I can supply all the part numbers to create adaptors to go between the harness and coil packs. Then no cutting into your harness.

I did this in my aux fuel install and it came out great, SI can comment in that.

Some companies selling aux kits charge $125 for plug and play adaptors when you can build them for $25 in parts.

I was just gonna hit you up about that. Maybe you should make them for sale. Get a little cash for that motor build :wink:

Im interested in finding out what adapters to use. Would make it easier to remove when im done with it

This! I'd be interested in making a pnp setup as well!
