Sun Dwell Tachometer Hook Up
I picked up a used Sun Dwell Tachometer to use when tuning my idle and advance. But I don't know how to hook it up. Its got a orange (maybe faded red) and a black clip. Where do I hook these up to check the RPM? I don't care about dwell, I rip points off tout suite. Thanks.
