installing aftermarket tachometer
Posted 06 February 2005 - 03:22 PM
Don't worry, I didn't get one of those super ricey monster tach's with the huge shift light... lol It's a little 2.5" one that I'm gonna put right on my steering column for that racecar look
Anyway, I'm trying to get it installed. I hooked it up to the battery and negative end of ignition coil and it works perfectly. now I just need to get it wired in the cockpit.
Drilling a hole in the firewall - driver's side: How thick is it? This is probably a bad idea, but it seems like all the wires for the dash come through on the passenger side. I guess I may just have to run the wire through there, but that's a pain in the rump roast. So is drilling, I suppose, I guess I'm trying to figure out what would be less of a pain...
What is the best wire to tap in to to get power and ground in the maze of wires under the steering wheel? It's such a mess in there!
There's a another wire that is supposed to go to the dimmer switch, I guess to power the light on the tach. Looking at the FSM, man, I can't find it. I feel like a total retard, At one point I was an electrical engineering major but these diagrams look like the sewers of paris. I am so terrified of doing something dumb and chasing electrical gremlins...

So I can just drill a hole in the rubber?
I don't suggest drilling holes in firewalls, and it should be easy to find a pre-drilled hole that is plugged with rubber you can use. It would probably only need a penknife to open a large enough hole up for you to pass wires through.

For the lighting option on the gauge, I generally tap into the illumination wire on the stereo. That way I don't have to wade through a huge mass of crap to find it.
