hey guys, i've looked around this place many times looking for info on my car, but i have a question to ask now. I have a 94 Sentra E and want to install an autometer monster tach in it but i have had some problems.
1. where do i need to connect the green wire to my coil. my car did not come with a tach.
2. where is a hole in the fire wall i might be able to route the wire through, or do i have to drill one myself.
3. can i connect the black wire to my radio ground wire

thanks for any tips or tricks you might know, i'm in over my head:(

I had an Autometer tach hooked up a few months back... let's see what help I can be. :D

(1) We spliced the green tach wire right into coil wire, and used some black electrical tape to bind it up. Worked great... just ran the green wire back through a firewall hole.

(2) The hole we used was above the gas pedal.

(3) Um... not sure. We grounded the black wire to a screw into the metal frame under that dash. Dunno if the stereo will suffice.

Good luck! :)

I'm no "Search Nazi" but did you use the search feature here to try and find the answers to your questions? You didn't look to hard, because I answered this question just yesterday and it's in this same forum. It's okay, just look a little harder next time, some people can be real big dicks about this. Mine's just smaller. :DClick here to read it

It's alright dude, I just have seen too many newbies get ignored or hollered at because they didn't obey the "search nazi manifesto". :)

Not to be mean or a jerk but if you have trouble installing a tach how are you gonna do a turbo. Not that I could at this point, mainly due to finacial reasons, but ya know

Pet peeve time. I don't understand why people go to all the trouble to drill holes in their firewall and hack into their coil wiring, when there is a tach wire abandoned in their dash which is where the OEM tach would have been connected if one had been installed. I guess people just like to do things the hard way as well as the wrong way.
