yea you can, the folowing is from Ryans site FORDFUELINJECTION.COMFoghorn said:According to ryans site you can even get the codes if the light is burned out and you don't have a scanner.......Sounds fishy to me...Fog
That the section I was refering to.....I just didn't post it. The "fishy" I was refering to was the mechanic saying it can't be done... Did not mean to sound as if I was Dissing the Guru. Sorry for the confusion....Fog:beerGacknar said:yea you can, the folowing is from Ryans site FORDFUELINJECTION.COM
If you are a lost soul that does not have a working engine light, or did not install a light into your dash don’t fret. You can still get the codes. You still need that wire to ground out the STI. Now you will need one of the following tools; digital volt meter, analog volt meter, test light, or you can hook up any other 12 volt light that does not draw more than 0.5 watts max.
