I picked up the tach for my truck today hooked it up and it worked for like 5 seconds and then started smoking, what could cause this?? I am 100% positive I hooked it up correctly, I checked the wiring like 4 times over to be sure, plus it was working when I first put it in. Do you think its just defective?

 

too much VTEC y0!

in all seriousness, it sounds like a short

 

damn i was gonna say that.

 

does it still work, or light up

 

Lights up, jumps when I turn the key on, but doesnt display RPMs and it keeps smoking.

I called today they are going to swap it out for me.

 

black - ground
white - light power
red - power
green - signal

If those are correct, then it's a defective tach.

Is this for the mexican truck or the mexican car?

 

LOL's.

 

damn. you found the hidden smoke! good job..that shits hard to do

 

The steering doesn't work that well in your old car anymore, btw spic.

 

.. it did work well at one time?

Steering wasn't exactly a top priority.. he's lucky it came with a cat converter and a passenger seat.
