If you do decide to put a bottle on it to catch any dripping, just make sure it vents. If it is sealed up tight, you will prevent the crankcase from venting and can cause other damage and likely more leaks.

Lots of things that can cause poor mileage. Tire pressure, tire size, air filter, dragging brakes. Do you have a EGT gauge? If so, are your EGTs high while driving?

This is what I used. They fit and work fine. https://www.amazon.com/gp/product/B00BF6HWFY/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 I used the 5.25" for the rear with no issues.

I bought inexpensive speakers off Amazon, I don't remember the brand. They are better than what I had.

You can get your APPS from this site.

Very nice. If my welding prowess were better I might attempt a job like this.

Fuses?

How does it sound?

I was able to reuse most of the plastic fasteners. A few did break. If you take your time and have something to help pry it apart you will be just fine.

I bought a bunch of the plastic door clips off Amazon. I still have quite a few, I can send you some if you are in need.

You could hot wire your IP, that would take the ECM and everything else out of the equation. If it still runs rough and cuts out with the IP hotwired you would know that the problem in not in the ECM. However, you WTS light flashing is indicative of ECM problems. I would think that if your ECM was on its way out that you would have more faults that than just those. Your ECM may be bad and your VP44 may be on borrowed time as well. Like was suggested before, you could call places that repair ECMs and see what they say. I would hate to see you throw money at an ECM only to find out that you overlooked something.

I did this a couple of years ago to my truck. i put aftermarket speakers in and it is fairly easy. I will try to dig up the post and you can see the pictures how I connected everything. Here is the post that I made with pictures. It is pretty straight forward. I did make a mistake and left my pillar tweeters out on my first attempt. I did have to go back in and rework that but that is mentioned in the post. Hopefully this helps.

I would start with the codes that you can pull with a scanner and not just depend on the key trick.
