i need help on how to run the wires from the tach to the engine bay. i will be installing the tach underneath the a/c vents. i have no clue how to get the wires to the engine bay. i dont really want to drill anything becuase i would probably **** it up. any suggestions or help would be appreciated. also i have a mallory distributor and the coil is internal. im not sure where to hook the green wire up. could i just find the wire that my tach is using now and splice into it? or do i need to get another connector?

 

i spliced my green wire into the one white wire CLOSEST to the front of the car from the coil
