Tach Question
I recently installed an American Auto Wire engine compartment harness. I then talked, by chance, to a tech that helped design the harness, and he said that I will need to run an inline tach filter if using the factory tach in order to get the proper RPM readings since I am using an HEI distributor. Has anyone who has installed the American Auto Wire harness come across this problem. I have not yet installed the new cluster with the tach into my truck so I am not sure what reading I will get. What do you think? I'd hate to be hasty and run out to purchase a tach filter only to find out that I did not need it.
