sorry the first is long, but i didnt want to leave anything out. thanks
1. My tach used to work before i took off the dash and now only the light comes on, no RPM. Its autometer. I know the black should be going to ground, but instead it was linked to a blue wire that is now not attached to anything, but i think it was going to the ignition switch, which i do not know where that is... The red wire that SHOULD be going to the ignition switch is linked to a black wire going to the battery ground. I know it worked before, so maybe i just need to find the ignition switch and link the blue(black) wire to it.... or should i link the original black to the ground and get the red wire to the ignition switch?
2. the tach backlight now only goes on with the headlights and stays off with the parking lights... where should i link the wire to fix this?
