Dimmer Wire for Tach

[mrrock]

Can someone tell me where to attached the dinner wire for the tack
I tried the wires off the back of the dimmer switch but they seem to be a non-variable sourse(can't figure out why!). I've looked at all the threads and I don't seem to find any mentioned locations. I would like it to be near all the fuses etc.

Can you tap into the dimmer for the radio?

[mrrock]

I assume that would be at the back of the radio and I need near the fuse box

just hook into the dimmer switch the green wire

[mrrock]

thanks, do you know why some of the others don't dim?

[KSIbucky]

be careful if you have a crappy tach it wont work

[mrrock]

[KSIbucky]
