possible conversion of internal 24v accessory rail to 12v in 86 m1009?

i hope that i am not breaking any rules here. But i was wondering if there was any info on changing the rail behind the pass front seat to run 12 volts? Or can i run a new fuse block from the reducer on the firewall?

Those rear buss bars are just connected to the 24v buss bars under the hood on the firewall. If you want it to run 12v, just remove the positive cable for the rear buss bar from the positive 24v buss bar and connect it to the positive side of the front battery. I would be careful what you run off of there though, as then all the load, as well as the rest of the truck, is running off that front battery.

thanks cpf240! i hadn't thought about the fact that they would only be run to the busses under the hood. All i am really trying to run is maybe a 12 volt fan or two in the back of the truck, for air flow...wet dogs stink, and any moving air is good air....
