The Junction block is the assembly located under the dash just to the left of the steering wheel. It contains 30 fuses and has many of the electrical circuits used in the Commander. Following is a list of the circuits that are on the Junction Block as well as a link to Chrysler parts for the Junction Block. There are several different part numbers for the Junction Block and it depends on the features for the Commander. If replacing it would be good to take your current one out and take it to the parts department for a new one. Today's listed price was $193.20. I will also include the write up from the service manual of how to remove and replace the Junction Block.

I don't see the nice detailed/illustrated photo that use to be attached to this post anymore.....that's unfortunate.

@rblapham do you still have the pic that used to be attached to this post? Maybe you can re-attach it if that's possible.....
Click the link at the top of the post and also see the attached file at the bottom of the post.

Do you remember what the picture was of? or did Jeep 's post fix it? I looked and do not have any pictures that might fit the post?

It was a photo of the junction block & different fuse blocks that had some drawing & writing on it......I assumed it was something that you made.

I'm kicking myself now for not having saved a copy of it over the years.

I did that, it's not the link at the top and it's not the PDF attached to the bottom; There used to be a photo of the fuse blocks with some circles & writing that was typed on it.....it was pretty nice, I don't know what happened to it;

I'm wondering if this has something to do with the change they made to the forum.....I know as of a week ago, the photo was still there.

Digging through some of your old posts, I found one of the photos; I'm pretty sure there was one more nicely illustrated photo similar to this that I can't seem to come up with - or maybe it was just my imagination and this was the only one;

Anyway, here is the one I found, maybe it will jog some memories for you @rblapham; I'm going to reinsert this back into your original post where it used to be; I have it saved now for posterity....LOL. I'm attaching another .PDF I grabbed off of one of your old posts too, this seems like a good place for it; see attachment.

Yes I found that one. Possibly this PDF has the others. That's been a long time ago and I'm not getting any younger.:frown2:

Too much valuable information in this thread to leave it buried in the archives of the Electronics / NAV Discussion sub-forum, so, the time has come to make this thread a sticky; Now it's easy for everybody on the forum to find if needed.

Many thanks to @rblapham for his contributions.
