lmc HD headlight harness gmc/4 lights

[C5Phil]

OK... I have the same lmc harness with the same issue (dim lit blubs on sometimes) on my GMC... I tried to follow this thread but got confused real quick-- the way I read through it there seems to be posted multiple solutions...Am I wrong? in any case I can't follow any of them (yes I'm electrically illiterate) could someone give me simple step by step instructions on how to install the screwed up LMC harness in to my 70 GMC? i'd be forever grateful.....
And I bet this would make a great sticky in the FAQ section--
