ok ive searched and cannot find it, i have a 1998 hyundai elantra 1.8 dohc i need to know the rpm signal wire off the ecu and the o2 wire im wiring a rpm guage and an air fuel ratio

 

Since the Tib and Lantra are so very similar in these years, this page should help.

thanks guys sorry for being a nuecance, wat about hookin up the air fuel ratio guage

 

any body know what wire to go to the airfuel ratio i know its an o2 sensor wire but wat one?

 

That one didn't work?

 

i soldered it already but havent tested the rpm guage yet

 

ok i started the car up and YESS it finnaly works, i now have a working rpm guage (;;; thanks to you guys, i just wanna apoligize for all the stupid questions i had but thanks again, only thing is i have to calibrate the rpms, right now the guage idles at 2.5k witch deff isnt the cars idle, wat should it be at so i can preset it (;;;

 

What gauge are you using?

 

swoosh sound active stepper guages, there pretty good, they work well for me at leaset and i like how you can change the colors on the dials and facia of the guage, good quality stuff to me, i want to get more but money is tight
