wsup everyone got my hids from operatic today ok here is my dilemma searching high and wide for a guide with little to no luck maybe i just suck at wiring lol anyway im putting my new h11 hids in my 08 everything hooks up well however where is the best place to put the ground wire at? can i connect it to the negative terminal ? and is it safe to unscrew battery terminals as long as i work on one at a time? like i said im a noob and also i connected the relay to the stock wire on the left side does it matter anyway if you could help this noob out would appreciate it thanks!!

 

Attaching the ground to the battery would actually be optimal if you can do it. If you disconnect the battery cables, disconnect the negative first, and make sure to not let it touch any metal part on the car; then remove the positive.
Somebody else will have to help you about the relay thing, I have no idea what you're talking about.

 

I usually find a spot on the chassis to ground wires to making sure to sand it down to bare metal if I have to.

Taking battery off = neg (-) first then pos (+)
Putting batter on = pos (+) first then neg (-)

The wiring harness can be connected to either side.
