Hi everyone...

I'm installing some indiglo gauges for my friend's JDM spec Jazz and i've removed the cluster, overlayed the gauges and i forgot one thing: i don't know what wire to tap for the headlights...

Can someone point me in the right direction as far as which wire is for the headlights, and a good place to ground the negative? (I don't see any bare metal bolts to ground the negative behind the cluster)

I could use a volt-meter, but that's just so time consuming and i still may end up tapping the wrong wire...so i want to avoid any potential mishaps....

Thanks, appreciate the help!
