Rodehard

I have an '07 Tahoe LT with the 5.3L V8, which is towed behind my RV to ballgames, etc...
I have installed the required transmission pump, light harness, brake box, et all, but this 2-wheel drive presents a new problem. The Tahoe key must be in the"accy" position to tow (Has to be on to shift into neutral, won't turn off unless back in park.) I have installed a toggle switch for the fuse that covers the radio and dash lights, but still have a battery drain somewhere.
Can anyone tell me the other fuse(s) I should disconnect. This would be much simpler than running a battery charging circuit from the RV since all those connector harness wires are spoken for.

Could you put in a battery disconnect? just remove all power?


Sad day when Stevie Ray vaughan passed, he was like family here in Austin

Thanks in2pro, a battery disconnect is an option we're considering. Curious if we can do this via fuses first, as chevys' postive post hookup doesn't lend itself well to a disconnect.
Clean, simple, easy is my first goal always, so it may be a disconnect after all.

Yes, SRV is sorely missed, but enjoyed and remembered daily on the cd player.

At the dealership that I work at they send the vehilces to have drive shaft disconnect installed. This way you do not have to turn on the vehicle. The customer just disconnects the drive shaft and tows vehicle. After adding rear (taillight tow wiring).

Charlie how does that work? would seem kinda a pain to have to get under the vehicle.. I think I'd rather do what rodehard was thinking.

hook up a push button to apply 12V to the tan wire of the shift lock solenoid. That way you don't even need to insert the key to shift when the button is pressed

The only thing I trully know about these disconnects is that they have a cable that is run into the cabin by the drivers seat. You pull cable and drive shaft disconnects. I do know they rebalance the drive shafts. I can ask the Acc. sales manager exactly what they do. I rarely see these vehicles since when they are done the customer picks it up and trailers it behind their RV's.
I will post his response tomorrow.
