Sorry to hear of the poor turn out Covid ruins everything. Your truck collection is great! My son loves cool trucks so I will prolly get one soon....
Hope the weekend is better.
Its not that bad, you have to run the wires from the ecm to the lap top. I would rest the lap top on the passanger seat and the cable to the ecm went into the footwell and under the dash.
If you are going to put any power to the 2004r transmission I suggest getting an expert to beef it up or buy a crate trans from Dave hussik or Lonnie Diers.
I had local guys do my trans 3 or 4 times before I realized you need a specialist in this trans to get it done right. I have since bought...
If it has only 44 miles on it I would take it to a big auction, lots of customers and media attention and a for sure sale. That would sell the car for sure and you could move on.
I just sold my Hard Top Cloth TTA with 900 original miles and got lucky and found someone who bought it unseen...
