You should be able to splice and solder on the back side of the odb2 plug. Extend the wires a foot or two.Get some .187" female spade connectors. Line up the pin side of the scantool to the odb2 plug. Use the female spade and and crimp them on to the extended wires. Plug in the corresponding wires of the odb2 plug to the pins of the scan tool. Then just zip tie the scan tool module some where secure under the dash. That way you don't have anything sitckin out of the front of the odb port and the dealership/mechanic still can use their tools without problems.
