Reverse switch leak and short
put tape on the wires but i still blow.a.fuse when in reverse. Only now the fuse pops when i let off of the clutch and not as soon as i shift. I disconnected the reverse light harness and it still shorts.
should i go through my fuse box and look for shorts?

I removed the switch connectors and now i can reverse but without reverse lights

Darkbrew, it's actually easier than that here.
acherry370, there is a wiring loom that runs from the engine bay along the top of the transmission back to where the shifter is. The last 2 connections that this loom makes is actually a set of 4 plugs, 2 black, 2 white. They are the neutral switch (white) and reverse switch (black) wiring. They run into the transmission to two sensors there to detect if the car is in reverse or neutral, so the ECU knows to switch over to the reverse or neutral fueling maps. If there is a short in one of these, it will blow the ign key fuse. Since it is only blowing when you put it into reverse, then the issue is with the wires for the black connectors going to the reverse switch.
If you can get under there and disconnect the black connectors (2 of them), you can leave them disconnected (tie them up out of the way) for the short term until you get home and can fix the wiring short. The car will still run forward fine and still reverse, though just might not behave as smoothly in reverse, and your backup lights won't turn on.
