Yep....Red/Lt Green....for the gauges, you want to splice to the Lt Blue/Red out of the dimmer switch shown below..... you'll be able to dim the gauges as well.......

 

if you are tapping into the wires for gauge lights u will use the dimmer. on the back of my dimmer i'm pretty sure i used the brown wire. then your gauges will dim with the dash lights. you can find it easily with a multimeter, that's how i found mine.

 

thanks alot..im very thankful for these forums and all your help.One of these days ill be helping others with the knowledge ive gained from you guys
