Small thing learned this week.....

The stock power wiring has one 2 gauge (black)and two 8 gauge (red & red/white)wires at the positive battery terminal. The black goes to a large stud on the starter and the reds go off to the fusebox.

In wiring the battery disconnect one needs to run new 2 gauge to the switch amd thence back to the starter stud. The reds then also need to be transferred to that stud. To get them there, their routing needs to be changed.

Remove the battery and unsrew the two 10mm nuts holding the red wires to the battery terminal. Undo the 10mm bolts to remove the battery support. Unscrew the captive allen bolt holding the power steering reservoir to the battery support. Now you can take the plate out of the car and see the wiring running underneath it. Free the bundle from the plastic clips and unwrap the cloth tape to free the reds from the bundle they are in. You will have to go all the way back to where they used to disappear under the tray. The new route uses the same path as the one for the engine ground. The lugs on the reds will have to be reamed out slightly to fit over the starter lug. Re-wrap to protect the wires, then assembly is the reverse of removal.

Special bonus feature! If you are putting the disconnect inside the car you need to run through the firewall. Looking from the engine compartment to where the various wiring bundles go through, you may see a plugged hole. Remove the plug and you have a 7/8" hole through; big enough for the dual 2 gauge and the smaller wires to kill the 12v side of the coil.

Have Fun,
