98 voyager elec problem

Alright here is what happened. I took out the factory head unit. I snapped in the wiring harness to connect it to the new radio. I wired the proper wires together. It didn't work. I checked all of the fuses including the ones in the unit. They are fine. I've done a lot of installs and never had this happen, So i put the old unit back in to see if that would still work. It doesn't. now here is where it gets a little wierd. When I turn the vehicle off, the power locks don't work and neither do the interior lights. When the vehicle is on, everything works just fine.

*edit* I read in the owners manual that there is an internal fuse that controls these things and if it needs to be reset I should go to a shop. Is there any way I can just reset it? Or isn't that the problem because those things work when the car is on? Any help would be wonderful.

Did you check all the fuses under the hood , in particular the IOD fuse . Pull this fuse and check and then reinsert it , this will reset the BCM which controls the locks and the interior lights . Let us know how you make out ...

There is no fuse labeled IOD.....
I thought about that but I couldn't find that one. Well not one specifically labeled IOD.
