i just installed a set of Dual Beam DDM tuning HIDs in my 2001 Mustang Gt. I ran into a problem, The kit only comes with one plug to plug into the factory harness, leaving one factory harness un-used. The dash light in the car came on, saying that i had a headlight out. I got everything to work though, by plugging in a regular bulb into the factory harness. I was wondering if anybody else has had this problem and what you did to fix it.Thanks.
