I have an '86 C10 with a 350, needing to install a heater core with a/c. I have coolant leaking in my truck, man that stinks! I am wondering how hard it is, I have some people telling me it's not too bad, but others telling that getting the cables on for the right switches is a pain. Is there any easy way to installing this? Anyone know of any how to's that make it easy for someone who has never done it to be able to do it? Any help would be appreciated.
