Ok i am a noob here but i have modified many cars. The 02cav is my wifes and i want to put the HIDs in her car and i have been reading and searching here for the tips and tricks and problems that others have had.

Now i know i need to disable the DRLs. I got that from this linky...

Now my second question is do i HAVE to purchase the relay? I have installed HIDs on my 07 G6 and i did not need it, i put them in my brothers Ion3 (9007 hi/lo just like the cav) and my sisters RAM. There were differing instructions about this relay but i never used one and never had issue.

As for the insall i bought the 9007 Hi/Lo DDM Tuning slim balasts. I also read here that the red wire is for the HI and the black is for the Ground and the blue is for the Low.

Once i install them are there any other issues i should look out for or have i covered all my bases?

Thank You

i would get the relay harness, mine worked fine for a while then started having ignitor issues on the passenger side. the relay harness fixed it. for no more than the harness costs you wont have to mess with it later. Mine are also DDM.

Do you have a link to the relay you used?

Also how much after the install did you start getting the issue?
