Does anyone have a DIY on how to install an aftermarket tach? I have a 99 civic lx. Any help would be great. Thanks guys.

 

there's only four wires to hookup.
red- 12+v
blk- gnd
illumination and neg wire on the coil off the distributor.
Look at the helms or fsm for more info. Most likely in a sticky post

 

I just installed mine and it was pretty easy.
Black is the ground. just attach it\screw it to any metal part of the body.
The tach wire (color varies to tach) will attach to the tach wire coming from your dash gauge. It should be a light blue wire. Just tap into that.
Red positive wire will need to be powered only when the key is on the on position. So look at your ignition(where you put your key in) There will be a thick yellow wire. Tap into that wire. The white wire or in-dash lighting wire, i dunno where to wire that, so i just wired it into that yellow wire also.

Have fun.

 

Thanks for the help guys. Going to get it hooked up this weekend!

 

i have a 96 dx and there are a couple of blue wires back there? which plug is it on?? left or center?

 

if you pull the center guages out(not fully, just pull it out and look over it.) it should be on the left, bottom i think. but its left
