This is for installing a second battery with a Stinger battery isolator. I have everything ready to install. The Stinger instructions call for connecting one of the connections to a 'true ignition source'. I don't really know where to connect this lead. The other three are obvious.

Any help here?
Pics/diagrams?

its easy, get rid of the resistor...it is not needed and will most likely hurt your voltage and charging of the rear battery

It's a relay, an not a resistor, correct?

Besides, my goals are not for car audio,per se but for pure battery protection of my charging battery. I am using this for deep-desert camping, with possibly days that I don't run the truck enough to re-charge a primary battery. Beside some very limited stereo use, this is also for lights, some camping gear, some low voltage electronics, etc.

Doe this make more sense?

alot of stereo shops tell you that you need a isolater, the only situation where a isolater would be helpful is if you had your stereo going for a long time off your 2nd batter, its main use is to drain the rear battery (your 2nd batter) first and leave as much of a charge in your front battery for starting the vehicle and stuff...so it sounds like it would work for what you need...however depending on the battery you get be careful...going from a charge to so low it wont even start a vehicle will kill your battery quickly

That's what I was trying to say in the first place. Besides, this thread isn't a debate on isolator use, it's about isolator installation, regardless of my intentions...but thanks for chiming in!

Granted, it's for an Exploder but it might have the same wiring.
I'm also on a quest for this wire for my Avic Z120BT head unit. When I turn over the engine, it drops bluetooth pairing during the reboot and interrupts audio playback which gets my man-panties all in a bunch.

For ignition you could tap any fuse that switches with ignition or go straight to the ignition harness

The trick here is to find "true ignition" which won't get switched off when the key is moved all the way to the start position.

go to the ecu ignition power on or directly to the keyswitch

use the isolator there are several reasons to use one!
