MAGNETIC PROXIMITY SENSOR: Classic Instruments
It is useful on trans-axle setups or transmissions without mechanical speedometer cable connection.
Using a stock GM Speed Sensor - 700R, 4L60, etc. Our Speed Pulse Convertor Box is used on late model GM 700-R or 4L60 over-drive transmission applications with a GM VSS (Vehicle Speed Sensor). This Convertor Box will convert the signals from the stock GM-VSS so your Classic Programmable Speedometer will read and operate correctly. The original GM-VSS signal can still be used to operate your fuel-injection, engine monitoring, transmission shift points, etc.
Tachometer Filter Our Tach Filter is supplied with most Classic Tachometers. Installed between the Tachometer and the Ignition Trigger Source (usually the coil) this filter traps, redirects, and dissipates the high voltage spikes and surges that are emitted by any late-model high-energy ignition system.
It also modifies the sharp up-and-down spikes into a semi-square wave signal for steady pointer readings and faster pointer response. Three color-coded wires allow for fast and easy fool-proof connections for life-time protection and superior response on all Classic Tachometers.
Classic Instruments was founded and continues with one simple goal; To be the very best in the world. That's why we work hard every day to remain the top choice of knowledgeable automotive professionals and performance enthusiasts since 1977.
