Blk(-) and Brown(+Red) are the wires once you Have the Fuel Sender Out of the tank.

The Wires for the pump if using the Pins on the Harness I'm not 100% sure of,..but I think its Blk/Yellow stripe and another one...oh well you'll see it when its out.Follow them to the wires that are Conecting to the Pump Itself.

Grab a 12v Drill batt and try them.See if it turns on but only check for a sec.

may have a Harness issue where it plugs into the trunk plug part.
