12 GA. Marine Primary Wire Needed

Have to make up a new wire from my starter solenoid to the battery terminal on my coil.



Does anyone know where I could get about 6-10 ft. of 12 ga. marine grade primary wire in purple/violet (for ignition) in North / NW Houston or Conroe? I haven't been able to find anyplace listed in Houston area. I need it by Thursday, so I don't have time to order any online. I see automotive wire everywhere, but I figure that only marine places would carry it and the ones I've been around lately don't have much inventory in wire. If you have seen anyplace with wire packages (marine) please let me know.



West Marine website shows 12 ga. in every color but purple (go figure). I am going to call them tomorrow to make sure. Again, if you know of a place, please let me know.



Thanks in advance
