Tach wire
trying to measure my rpms on my truck at 60 mph. it is a 2002 ls1 with 460. My question there is one wire on my harness labeled tach from my harness builder. What signal is it putting out? Can I just connect an old school tach to it and will it work. Not looking for a long term solution just want to see what my rpms are. See if my overdrive is working.
