Hmm, 4 wires to the pump you say. I'm not familiar with the 1st gens but I do know that it is mechanical. At least two of the wires should be for a fuel shut off solenoid, the other two, I'm not sure of. The two running to the Intake are your power source for your heating grid, I'm assuming you are talking about the ones located at the base of the intake horn. As for that black box, I'd have to look at it to be sure, but it sounds like your main fuse box, which also contains several relays and such.
