Replacing upper wire harness, what else can I do...

[Alex89]

I will change my upper wire harness really soon, so while doing that what else can I do... I was planning on spark plugs and possibly vacuum hoses because they are pretty stiff last time I checked (when I was changing the air filters).

Where can I find a vacuum diagram with the part numbers? I found this but I don't think its exactly what I want. If I remember there are more hoses than what I see in the pic...

Anything else I can change?
And wire harness shouldn't be too hard, unplug one thing from the old/current one, plug in the same thing from a "new" one..etc...right?

Thx!

Not a lot of vacuum hoses- are you thinking of the PVC hoses? Be gentle with the wires especially if your ETA is original...

Yea all those hoses under the air filters...I want to check them all. That's why I would like to see some kind of a diagram so I know whats what exactly....

Read this thread, it should have all the info you need:

Replacing the vacuum tubes is also a good idea, those are cheap and there are only a few (one to EZL, plus the vac lines for the EGR and smog/air pump valve).

Oh wow, amazing. You are the man! That's exactly what I was looking for!
