I'm trying to find out where the power distribution block is located on an 86 Iroc. I think the wire going to the block is bad and needs to be replaced.

Is the orange/black wire (that goes from the fuse mounted in the engine well right by the battery) the one that goes to the distribution block? Right now I've got power to interior lights, radio, a/c, headlights, windshield wipers, etc. But I have no power to power door locks, rear hatch motor, fuel pump relay, and starter. Would a power distribution problem cause these symptoms? When I unplug the orange/black wire, nothing changes at all to the symptoms mentioned above. It appears the wire is currently doing nothing, which makes me think it is the culprit.

Thanks for any help. I've already looked at all the schematics on austinthirdgen, and I've searched the forum and google for the power distro block location. If the info is there I haven't seen, and I apologize. Thanks again.

 

If anyone knows where the power distribution block is, help would be greatly appreciated.

 

It looks like what I'm looking for is S163 on this wiring diagram. Does anyone know where this is mounted on the car? Is it in the engine well, or maybe is it under the dash?
