Anyone running one in a 2002 neon and knows where to get a correct wiring diagram for it? and are you using tha tach adapter or not i have read multipul posts saying its not needed.

Hows it working for you?

this is the one i used for my 2000 and it work fine

I have the one Alex had in his 2001 neon. as with yours he also used the tach adapter.

Using same diagram for mine with 02 R/T harness.

Works fine.

Without tach adapter tuning is limited on safcII to throttle position, no clue about neo.

I'll go out on a limb and say tach adapter helps fine tuning since you can also tune by rpm and not just throttle position........but it will work since the tuning is roughly 60-70% TP biased and 30-40% rpm........As you have already read.

I'd suggest an accurate wideband and a "new" 02 not someones used wideband 02. There is enough tuning available with one to kill an engine rather quickly.

Sidenote avoid 5 in 5 out setting. Use 4 in 4 out or 6 in 6 out.

I`m running w/o tach adapter and i tune by rpm.
