BTW: to answer the wires quest
BTW: to answer the wires questions....
to the large solenoid lug with nut, goes all the hot wires - battery, alternator hot wire, additional solenoid power feed. They should all have round connectors on them to slip on the lug and be tightened in place.
to the push on connectors on the solenoid - you could have 2 or 3 wires - one larger wire from the ignition switch to energize the solenoid from the switch for starting ( this may have been rerouted to the aftermarket solenoid in which case you should have 2 wires left), one smaller wire from the fuel pumps relay/s to energize the pumps & CS injectors for several seconds while cranking, and likely a third wire from the Aux. afermarket solenoid that adds additional voltage for troublesome stock solenoids.
If you have extra wires unaccounted for let us know and we'll continue resolving the issues.
