I am thinking I may want to add a tachometer at some point. My dash is in the car, but still tilted downward and I can reach and work behind it if needed, so I am thinking now is the best time to prepare wires for a tachometer. If I understand correctly, an aftermarket tach will need 4 wires......
1)- sender wire to coil
2)- 12V to ignition-
3)- 12V to dash lighting
4)- ground
When connecting the 12V to dash lighting, am I best connecting to the dimmer switch so that it dims along with the rest of the gauge lighting or just connect it to the switch so that is "on" at full brightness when the lights are on, and otherwise "off"?
Where is the easiest point to connect to 12V ignition? I don't imagine this will be to difficult, and was thinking I will probably just go back to the fuse box with this one.... but would still like to hear suggestions?
Does the sender wire to the coil have to be kept apart from other wires to prevent interference?
I am not sure of location of my tach yet......I know it won't be a factory one in the gauge cluster as I wanted to keep my clock. I was thinking either on the steering column or under the dash in front of the console..... wanted to get my dash and steering wheel and seat all in place first and sit in it for a bit to see where I would like to put it.
I am looking forward to hearing suggestions from all those who have done this before, as I am sure there is much to be gained from your experiences!
