Description: Pull Up Resistors (Set of 5: 470, 680, 1k, 4.7k, 10k Ohms) Many ECU outputs are low voltage (4-5V) which will not drive a Marshall tachometer without modification. If you have a low voltage (4-5V) tachometer signal you can install a 680 ohm "pull up" resister from the 12V gauge power wire (ACC) to the signal wire to increase the signal strength. Connect one end of the resister to the 12V ACC wire and the other end of the resister to the signal input wire. Only install one of the resistors. Use the highest value resistor that works for your signal strength. A 680 ohm resister will work for signals in the 4V range. A higher value resister (i.e. 1000 ohm) can be used if your signal has a higher strength (i.e. 5-6V). NOTE: Make sure your tachometer has a common ground with the signal source (ECU).
