I am installing a tach in my car and have run into a little difficulty. Where is the best place to terminate the white wire so the backlight works through the rheostat and dims and brightens with the rest of my dash lights. Do I have to remove the switch?? I hope not, it looks like a project just to get to!Thanks,
Barry

Thanks, I'll look at that tomorrow. I started up the car to see if the tach works and low and behold, the $#%T$ oil pressure guage don't work.  I guess all my poking and prodding has messed it up. I got frustrated and just decided to walk away. I'll start fresh tomorrow.[This message has been edited by Barry70Stang (edited 11-11-2006).]

 I learned me some stuff today, through the school of hard knocks. Mike, your idea of tying in to one of the dash bulbs ended up being a learning experience. The whole dash panel system works off an electrical ribbon. The bulbs for each gauge just push in and twist and they contact the ribbon, there is no wire going to them. The same is true for the gauges as well, the gauges are bolted down and contact there respective area of the ribbon. There is a pin connector that ties into the ribbon that has the wires from the various sending units. The problem with my oil pressure gauge was that the wire from the oil pressure sending unit had been pulled out of the pin connector. I ended up pulling the dash pad and gauge panel, the learning experience made it all worth while.Barry

Barry, if you are just going to piggy back the wire onto another wire then run off one of the wires that illuminates the heater control panel. The light operates with the rheostat IIRC.------------------

Yes, that's how I light my Sun tach on the '72 and it works with the rheostat.

I ran mine to the light wire that goes to the shifter. Real easy to hook into at least on a 65. 
Because us 65 Mustang guys don't need or get NO heater control lights.

Thanks fellows, I didn't think about that. i wired it to where it comes on when I turn the headlights on, but it is not through the rheostat. I think I'll go back and change it. It would be  to have ti dim with the rest of the gauges.Barry

Yup, it also helps to fill those long winter days while sitting in your car dreaming of driving it. ------------------

I have several of those winter time projects lined up, Grenada disc brakes, heater core, air conditioner work, perhaps a set of caltracs. Barry
