Hi guys, how's it going? First off I would like to say that you guys have a wonderful site. Keep up the good work. Here goes my question. Does anyone have a shift light from Harlan? I bought one hooked it up and it only works at half the rpm eg. I set it for 5000 rpm it goes off at 2500rpm 7000 it goes at 3500 you get the picture. I have an 03 Silver and Grey. Maybe I tapped into the wrong tach wire. I have the cylinders set at coil per plug. Any help would be greatly appreciated
