low beams and rear running lights on passenger side used to work until i replaced the high beam headlight connector and now i am completely dead apart from brake lights and blinkers. Have tested it with a multimeter power is making it to the connector, the bulb is brand new - What would cause it to affect the other bulbs/connectors? Please help!!!

I would check the fuses first this guide can help. You may have popped the fuse when doing the repair.

Here are the wiring diagrams for the headlights and blinkers so you can see which fuses to check and how the system works. Check out the images (below). Please let us know what happens.
