Would anyone know which wires to tap under the glove compartment for always-on 12V in a 2006 rx330? I read somewhere to try the blue-yellow and brown wires, but that didn't work.

If you wanna do it pro, then just run a wire from the bat to the socket. Otherwise get a volt meter and see which one is hot at all times.

Thanks for your reply rgarjr. Pardon me for the stupid question, but is there a way to test for hot wires without damaging the wire insulation? There are about 50 wires in the vicinity of the glove compartment, and I would really like to avoid stripping them one by one to test for current.

Does anyone have the wiring diagram for the rx330? If so, could you please do a HUGE favor and see if there are any constant 12V / ground wires near the glove box? I would really appreciate it!

As far as running the socket to the battery, I am hoping I can avoid that to avoid the extra mess in the engine compartment.

I'd be sure to put in an in-line fuse for protection, whichever way to do the installation.

I will definitely put a fuse inline.

Could someone with the knowledge of the electric system please help? I am still stuck. What is the recommended way of wiring a lighter socket near the glove compartment? I was hoping I could pull some wires to the fuse box, but it is quite far (driver side) in an rx330. The battery is also not easily accessible. I would hate to have to damage wires one by one until I find the right one. Would anyone know the wire color of a constant 12V source that is accessible by removing the cover under the glove box?

Anyone? Please help.

Get some meter lead clips...like these...



And use a needle on the positive lead of your meter with the negative hooked to a known-good ground.

You can use the needle to probe into the wires and not have to strip them. While you are puncturing the insulation, you're doing the absolute bare minimum of intrusion.

I would also suggest that you not probe all of the wires in the exact same area...mix it up a bit.

That's my suggestion.

If you can string a wire to your fusebox, a nice touch is a little thing, I believe it's called an "add a circuit".

You find a fuse which is protecting an always hot circuit, then install the "add a circuit" to it. http://www.partsexpress.com/pe/showd...number=071-585

This basically adds a fused connection to your fuse box without cutting into any wires. I use this to add in my XM radio. Then I can pull the radio later, when the truck goes back to GM, without any damage to the truck.
