i know they are not labled a b on the A/C and i dont think they are labeled abcd on the alternator... so how do i know what is what... ? Go to autozone and find the plug to the alternator there... it should have colored wire on the plug then just match it up to the harness...
And for a/c are you asking which is low pressure/ high pressure?
