Help! Pretoria System

hi guys so I'm trying to finish up exploring altair I've done all the coalition space just finding my way through domkavash space in altair but I've gotten a bit stuck so I come out spica to Pretoria but I cannot for the life of me seem to find the Tonga Jumphole/jump gate so I decided I'll check the wiki out then ill go from there but it also doesn't seem to be displayed on there either can someone either tell me the location of Tonga although I would prefer it if this could be private messaged to me incase it ruins a surprise for someone else but as I said I checked the wiki here : Pretoria - SWAT Portal and at this point I'm totally lost i just wanna get to Hyperspace and back to new Hong Kong but someone need to let forlon know so he can update maps accordingly thanks guys

thank you Kindly indi !
