i installed an r1 tach in my car yesterday, i had first tapped into the dimmer but the tach wasn't working properly so i spliced into the cigarette lighter and it works fine but i have no gauge cluster lights and climate control lights. fuses aren't blown, what can i check, no blown fuses and all wires are securly taped.

 

underdash-relay hopefully is a the prob

 

thanks for the response, where is the underdash relay and how do i fix it?

</TD></TR></TABLE> Do the park lights work? if so and the fuses are good then it may be the dimmer control, pull it and check to see if you have power into it , [when parklights are turned on] and controlled power out of it when you adjust the dimmer, if no output you need to replace it 94
