I'm rewiring my gauges in my FD and I'm wondering if anyone knows where at 12v constant is that I could tap into? I know that there are various 12v switched around but I need a 12v constant for some of the memory features of my gauges. I've been searching but I couldn't find anything about possible constants to tap into in the interior fuse box or maybe a constant from the stereo. Any help?

 

Constant 12V+ Black/Green Ignition Switch Harness
Constant 12V+ Blue/Red Radio

also a 2 dollar test light does wonders from the parts store
