Are you sure about what it won't tell you?  Or am I misinterpreting 
what you said?  I don't have a wiring diagram in front of me at the 
moment but I'm quite certain I think I remember that on the GT6 if I 
disconnect the PDWA wire neither the brake nor the oil pressure light 
come on at all.  I know this because when I bought the car a DPO had 
done that very thing because the PDWA was stuck.  I re-attached the 
wire and both lights started working, with the brake light on all the 
time.  So I took the PDWA apart and freed up the piston.  If your 
wiring is the same then someone must have made it different, if you 
know what I mean.
