Hello Everyone , I've been lurking for several months but didn't realize I have been a lurker I owned a Ford F100 yearrrrrrrs ago but recently purchased 1974 F250. I have overcome several issues already but still have lots of questions. Thanks in advance for every ones help and patience, I might be an electrician but auto electronics is a whole different story but willing to learn (floating ground, hmmmmm, that's new to me) .http://www.fordtruckfanatics.com/forum/images/smilies/headbang.gif
