What harness? Is yours a 69 351w? Pics? I really want to keep it stock and just get the belt and pulleys. I have had my motor out and the 66 off the road for too long now. Been off for 2 months and should have taken me only a week to put in the motor. I am having so many problems and getting sick of it... I work on other peoples cars all day and come home and dont want to work on my own anymore and so when I run into problems like this I dont even feel like making something like you mentioned, etc. I'd rather go broke and spend the money and not the time. lol Guess that is what happens when you try to make a living working at a shop... you make very little money and no time.
