This weeks been a bummer.My mechanic knocked off a couple lines while replacing brake lines and now it won't shut off with the key.The brown line to IP shutoff is connected and the shut off works.The 4 way connector with the brown line to the firewall has an open port.What should this connect to?Also,the black line from box on valve cover to the three way connector to another black line has an open port.Nothing is connected to the line from the vacuum pump,the connections are broke.Just took it to a european car place and they won't even look at it.Too old,should'nt be on the road...Could someone with an 84 post a pic? Thanks
