<noembed><nolayer><div style="position:absolute; left:0; top:-100; display:none;"> LM-1 RPM Converter<br> picture - The LM-1 works with an optional RPM converter shown velcro&#39;d here. The unit has 6 inputs for analog sources such as RPM, TPS, MAP etc. I use only the first input which is RPM. The yellow wire goes to a jack I installed on the A/C vent that provides a convenient tach output for the converter. </div></nolayer></noembed>
