Something is shorting only when in reverse.... Maybe check the Neutral Safety Switch on the side of the tranny.

I should have said this before... I'd also track down a FSM and start examining wiring diagrams... Might be able to figure out what is on the circuit that only gets used when you're in reverse...

Wes - I e-mailed you a PDF of the wiring diagram for your 1994 XJ. ;)
