dont bypass the melter ares, replace them. Sometimes Ford uses multiple wires to run ground and leads from other 12v sources. Its like tapping into 1 12v source going to the rear of the car instead of running 14 for each different thing back there. Make sure your grounds are grounded and you may have some inline fuses along the way but Im not sure where they would be on your 94. Tear out all the lining in the trunk area and start searching everything, if this problem persists you can make a jumper, but I do not recommend this unless you are in a last ditch effort to get the thing working.
