Tach
 

I've got a 2000 Protege DX. Which, as you may or may not know, means no Tach... I know they're available pretty much anywhere... i'm just curious... which one to get? And one i get that far, how would i go about hooking it up?

2 choices, goto a junk yard and get a gauge assembly that has one, it plugs right in, no mods.

if you buy a aftermarket tach, but one that can be calibrated to a multipulse signal or it won't read correctly, it will be close, but not perfect. you hook one wire to your a ignition wire, another wire to you like control so when you turn on your lights, it comes on, then under your hood, on the driver side behind the strut tower there is a diog. port. you will tap into a purple wire with a black stripe for the tach signal. and you will have to run a ground wire.

So if i got a guage cluster with a tach already in it there's nothing else to do but plud it in? It'll do the rest by itself? Wouldn't the mileage showing be different as well? Not that that's a huge conceern.. as long as it wasn't higher than what i have now.. How difficult is it to take out the guage cluster?

its not hard, its just a few screws, maybe a hex or a star screw but not sure, if you take the cluster to a dealership, they should be able to reprogram the millage for you, but i don't know how much they charge.

I was under the impression that you couldn't do a simple gauge cluster swap on a dx because they don't have the correct wiring behind the dash for it. I think somebody on here tried that and wound up having to sell the cluster they bought.

its in the FAQ

are you familiar with any tachs that have a multipulse signal like you stated? Does Ractive tachometers have them?

not sure about reactive. any of the autometer gauges except the autogauge series have them. if you buy a tach that doesn't have the option for multipulse signal, then you will have to buy a tach adapter for 60 bucks fro autometer that converts it from multipulse to single pulse.
