In answer to your relay identification question. Look at the sides of the relay. There should be a schematic of the relay function. The schematic will match the schematic for the relay shown on the wiring diagram. If the relay schematic is the same on all of the relays then it doesn't matter which socket it is put back into.

If fuse #5 still blows with the ECM, starter relay and fuel injection relay out of circuit then it's going to be the alternator regulator - OR - you have an intermittent short in the White/Pink tracer wire that's shown as the feeder for all of these components.
I'd try to get the plug out of the back of the alternator first before removing it completely as then you should be able to pin the fault down. Unfortunately, said plug is a pain to get at while the alternator is still in place, and it's a tight fit into the alternator socket. One member resorted to snipping the leads and re-making the connection to get everything on the workbench.
Once you have the air filter box out of the way, as it's a '97, you're going to find a suppression module underneath it which has to come out if you want to get the alternator from the top. The bolts for this are difficult to get at also - I used about 18" of extension from underneath to remove them.
Just another one of these jobs that isn't overly difficult; it's just time consuming getting everything out of the way first. The suppression module was dropped at some point which makes the job easier.
Good luck - you've eliminated most of the possibles.

Thanks!
So I have to remove the upper radiator hose, cooling fans, and the suppression module. I knew about the first two, but not about the suppression module. What is it? What does it look like? I did not see anything in the way of the alternator. Here is the picture of what it looks like now.
Thanks again!
