now i brought a monster tacho a few years ago and put it on because my tacho inside my car was not working
now i (friend of the family) wired my monster tacho into the same wires of the original tacho and then both the tachos where working. now im sick of the monster tacho.
question time if i cut the monster tacho wires and put electrical tape around it will my original still work.

i would asume so, as long as there are no damaged wires to break the circut...

then again i dont have alot of experience with tachos...

should be able to chop the wires off, wrap them seperately in electrical tape
bundle them togther and cable tie them somewhere so they are neat and tidy, but also make sure they dont make contact with anything else

or you could trace the wire and find where they join the factory wire
then cut and tape afterwards
