Hood tach signal
I recently changed from an MSD ignition system to the Holley hyperspark system. My hood tachometer had received the rpm signal from the 6AL box. And now I've had to change my hood tachometer wiring harness. I've found the brown rpm signal wire from the hyperspark. Other than the obvious ground black wire fromthe hoodtach, I'm unsure which of these other 2 wires go to the signal wiring .I'm thinking one of the wires go to the lighting and the other to the rpm signal wire. Any idea? Thanks
