Need help with plug location

I've done some searching and I can't really find what I'm looking for. I have a loose plug on the drivers side of the trans towards the bell housing by the exhaust. I've crawled under several times to see where it goes and I can't seem to find the spot (used a flashlight and felt around). Does anyone have any pictures of the plug locations on the trans? :dunno: It's an AW4, brand spanking new, on a 1990 XJ with the Renix I6 with an NP231 Transfercase.
