Exclamation Installing a tach in 2002 civic

I am trying to install an aftermarket tach into a 2002 civic. I cannot locate the coil in order to get this thing hooked up. Any ideas? It's a 1.7L LX.

Re: Installing a tach in 2002 civic

1. The four wires from your aftermarket tach are red, green, white, and black.
2. The red, white and black should be easy.
3. The green wire goes to your test tach wire located by your battery. It looks like a coupling just pull it out and the blue wire is exposed use the green line off the tach to that.



Red line > I put to the 3rd fuse in dash
White line > I put to the right headlight fuse under the hood
Black line > To the chassis as close as possible to the tach

Re: Installing a tach in 2002 civic

I am going to be getting on this tonight... so the wiring will be the same even though my car has no factory tach? Please advise, thanks.
Also, is it pretty straight forward to put a cold air intake into one of these things?

Re: Installing a tach in 2002 civic

If ur looking for the tach signal wire, its in a small black rubber cube behind the passenger side headlight. Splice the green tach wire into the purple wire to get the signal. Try this out there isnt really much more to explain. I had dont this on an EX..THe VP, DX, LX should be the same as above or what I have written right here.
