black can go to any metal and I took my headlight switch off and took my multimeter to the back ofit to find out witch wire was the hot when my headlights turned on, sorry cant remember the color and T-Tapped the red wire on to that wire...

 

green wire. big one.

 

i didn't read what was said after your post. mine did the same thing come to find out YOU DON"T REMOVE THE NEEDLES it WILL ruin the gauges. sorry to tell ya and sorry if this was already said.

 

i got the same thing off of ebay the work great and look great but you can't remove the needles. i would recommend this product to everyone and there grandmother. but you gotta work around the needles just takes time and plenty of patience.

 

i removed the needles like 10x and it works fine[&:]

 

would someone like to be more descriptive than the green wire as i see about 3 or 4 green wires and i dont feel like splicing all of them. How about a pic or something of the wire?

 

i dont understand how the blue shows thru if the yellow lights underneath glow? do u have to remove the old guges first, i am thinging about buying the same item on thursday

 

I have mine on but havent wired them up yet ugh. Well at night u can barely see any glow off the old gauge overlay. It just peeks through. If you get some make sure when u install it there completely flat trust me took me a few error tries. (Like 57) hah

 

do u take off the old overlay?

 

no u gotta leave it on for the signals and check engine light and such. do not take off the original overlay
