96 mustang ?

Jan 09, 2005 11 Replies

i have a 96 mustang 3.8 v 6 . i just installed a 04 3.8 engine and i keep getting a lot of error codes , plus it isnt running right. does anyone know where i can find a wiring diagram, that includes pin location in the connectors ? for both 96 and 04 models?



Well, you can try the cheap-o Haynes and Chiltons manuals, but their diagrams never seem to be quite legible.

There's AllData. Maybe your local library has a subscription like mine does.

There are always the factory service manuals and wiring diagrams:

(2004, $60) and
formatting link
(1994, should be the same as 1996, $12)

I hope you used the computer that matches the motor...

i used the factory 96 computer and wiring harness . thanks for the help!

Well there ya go. You probably need the computer & harness that goes with the 04 engine.

96 is OBD2 and if 94-95 wasn't they'll be different.

Is this true? The Ford website still lists it as a 3.8L I have an '04 and was not aware of this. Pretty interesting though.

Yep, it is true. :) I am not sure why Ford changed, but they did have a running change in the 2004 V6 engine from 3.8l to 3.9l. Of course, Ford then changed the V6 again to 4.0l for 2005.

frosty289 opined in news: snipped-for-privacy@localhost.talkaboutautos.com:

All sensors and controls for the original engine should be used, including injectors.

Are the firing orders for the engines the same?

Should work.

I suppose you didnt burden us with extraneous info, like what the codes are, because you want to do it all yourself.

i'm not sure about 3.8 or 3.9 it looks the same as any 99 - 03 [ xr3 ] part numbers. how can i tell the difference ?

I looked under the hood after reading this post and discovered that mine was in fact a 3.9L It's written on at least two tags....one on the underside of the hood near the front edge, and the other on the engine near the oil cap. Check it out. The 3.8 and 3.9 engines are not actually very different at all. Ford states that there are absolutely no differences in hp or torque.
