Re: OEM diesel 4k tach
Is that tach electric or mechanical? If it is electric, you'll need to figure out if they used a 4 pulse signal or not like the gas tachs are. If that is the case, you machine 2 more grooves in your vibration dampener and use the dodge pick up sensor. You have to solder in a 1k ohm resistor in between the hot and ground wires of the signal wires for the pick up to work. Ive read of it being done on 4btswaps. I have not done it on mine but am going to someday.
