Oh man. Did you drink your coffee today?
Go back to this site by clicking on the link. I'll repeat it again here:
Scroll down past the image of the car, the reference to the Wiring Diagram via AllData, past the Ads by Google, till you see Download | Mirror and right click >> save as.
Click on Download.
You'll find 113MB of a zipped up .PDF Service Manual for a 1994 Toyota Corolla. Included in the .ZIP archive is a 307 page .PDF wiring manual. I'm looking at it right now.
It truly doesn't get much better than that.

I have a 98 Corolla with 120,000 miles on it. It's been burning oil. It runs great but I am just concerned why is it burning oil. I know these cars go past 200,000 miles but is it normal to be burning oil this early?

See post (2/25/07) #2820 & 2748 (1/10/07). I also replaced the engine on a 2001 4 cyl Corolla, Jan 07, with 84,000 that was burning 1 to 2 quarts every time the gas tank was to be filled since about 64,000 miles. The piston rod finally broke and that was it. We unfortunately purchased it with 52,000 and had no recourse with Toyota Customer Service.
Apparently this was an inherent problem with theis engine so we had to be very concerned with a replacement engine block, etc. This was a year ago and so far so good.

I have the same year, same problem as yours, I tryed every thing, could not fine the problem why my oil was disappearing, So a Summit Racing Tech. told me to switch brands of oil, So I switch from Castrol 10/30 to Penzoil 10/30 and this helped a great deal, but I still loose oil but not to bad at all now.

my 98 corolla number 1 piston rod broke and went through my block, this engine ran perfect, there was no explanation for this to happen, So I put in a 99 engine in place from the auto wrecking yard, and this one is running good but I have a oil disappering problem, no leaks, and it does not look like its burning it, as I switched brands of oil and that did help alot but still not perfect, So some of these engine do have a major problem thats hard to explain.

it's possible it's a stuck PCV valve. it's an easy thing to diagnose and cheap to replace if the internals are "gummed up".

It's either burning or leaking, no other possibilities. A clogged PCV can force the oil out in areas you might not see.

Okay, then it's time to get a cylinder leakdown test. That will pinpoint the issue I think if the damage is internal.
You can also put a dye in the oil, then lift the car and shoot a black light on it, and if there's a hidden leak it will show up with the light.
How much oil are you losing, say per 1000 miles?
