Wiring Problem

Ok so while I was wiring my wideband I must have hit something. My fuel level gauge no longer works and neither does my throttle position sensor. I changed the throttle position sensor and its still the same. I am at 0% throttle position no matter what according to HPTuners. I have a little light bulb volt tester thing, and I got the pins on the maf and IAC to light the bulb up but the TPS wouldnt light it up. The fuel gauge will go up like when i first turn the car to ON, but after that it goes right down as low as it can. I think my car is in limp mode now though because it wont shift until like 4k rpm. Im throwing codes for fuel sender low voltage, TPS intermittent voltage, TPS low voltage, and fuel sender high voltage, or something like that. I really dont want to trace down the TPS wire, is there something else i should check?
 


No surprisingly. I think i just grounded the 5v reference circuit that goes through the TPS and MAP sensor.
