can these be replace without buying the whole 300.00 factory harness? I have gone to local parts stores and they have a part but the dealer (the snakes) say I can only use the whole harness they sell. PLEASE HELP!

also I was told I need to relpace my upper rear control arm - would that be just the "bushing" or do I need more?

oh yea and one last thing....I just had my ABS module replaced and now my washer fluid leaks...of course the shop says they never touched it and it would be 2 hrs labor to check into it. any ideas what they may have bumped?

thanks
Alicia
