CCPU's are much like coupes and tudors that had electric wipers. I can send you instructions on how the wire is run on coupes and tudors, which is pretty much the same as CCPU's. It isn't real easy as you have to remove the cowl kick panels and the A pillar garnish and upholsteru panel above the windshield (which you would probably need to do anyway). Send me an email to:
[email protected] if you want the instructions. My coupe is a 28 and your pickup appears to be a 30 or 31, but I believe they are much the same, but not knowing much about 30/31 vehicles I could be wrong, as my wife tells me all the time.
