What are the pages you’re referring to for this? Do I need to pull the cluster to get to these connections? I traced only 1 wire from the kick panel fuse box for this fuse, but it went under the dashbut I couldn’t trace it very far before it was lost in the nest…Ok. Lets figure this out.
I'm going to list as many wires as I can that go to the 7.5A GAUGE fuse and then we can check on your car if it is right vs the engine harness.

Possibly more, I ran out of time to look.
THAM is air intake temp sensor manifoldHere’s what my 16 pin looks like:
What are these abbreviations?
The tach will not sweep. This is a 30 year old car, they never did that.Ok had to take some time off from car stuff but back at it now…redid all of the grounds from engine harness, black wire(AC magnetic clutch) has voltage with ignition on…7.5 fuse blows as soon as ignition is set to on position, tach does not sweep when ignition is turned on(same fuse)…
I am using the electronic PDF 1993 USDM SW20 MR2 wiring diagram document.What are the pages you’re referring to for this? Do I need to pull the cluster to get to these connections?

That is not normal. The red wire is not meant to be connected to that. The heat shrink is not OEM. They never used that, it was just tape.Just discovered that it’s connected to 2 under the fuse box: white w/black stripe and red…?
It definitely could be that. If that's for the oil level light then it's not needed. And if it's blowing the fuse then definitely don't have it connected.Could be this…?
That code can show up if the engine is cold.Couldn’t find a jumper connection that would blow the fuse in the cluster…checked the code as per BGB and it’s throwing a 21 which is oxygen sensor/o2 sensor heating circuit…
