Default 07 LBZ install

I am installing Ben's box on my 07 LBZ and am wondering where y'all tied in for the 12v switched hot that is hot during running and cranking? I just do not want to hook it up incorrectly and fry something!

Thank you,

Paul

I cant remember which fuse I tapped into on an LMM recently, but if you have a test light, use it in your fuse options while cranking to verify which ones stay hot while cranking.

the dirictions i got were for 07.5 and up trucks and the wire indicated to splice into for power and ground is not the same for my 07 classic. For my truck, on the BCM (found under the dash under the steering column), i pulled the plug closest to the passenger side, its the light blue plug, in that plug you'll find a white wire on the "A" side of the terminal in the #3 location, this wire was a hot source providing 12v in accessory, crank and run positions of the ignition. For the ground, i used the black wire with a white stripe found in the middle plug of the BCM(brown one), located in the A6 pin position, iirc. i went to radio shack and got the same wire taps ben uses to tap into all my connections, soldering them all to insure a solid long lasting connection, I soldered the t-taps by using them to make an indent on the wire, then carefully stripped the space between the two marks,then inserting the stripped portion of wire into the t-tap and heating the poles on each side of the tap till it melted the solder while holding the solder to the middle of the wire between the poles, it made a real nice connection.

I'm guessing this worked?

Anyone else wire up their bt l/u box like this?
