So im looking to check my timing on an 89 5.0 . I looked at the spout connector. And its not even plugged in anywhere its capped off? How can I set my timing if thats not connected to anything?

Thanks

 

That's it, it's just a jumper.

 

Just a jumper? Im a little confused

 

The SPOUT is a jumper that connects the PCM, engine computer, to the Ignition Control Module (ICM). It looks like this:


By removing the "jumper" you open the circuit between those two components. The PCM is no longer controlling the timing of the spark. That is how you set the base timing.

 

I've got some info here that might help you understand it a little bit more too.
