Thanks for the replies. I looked in the 85 FSM and you are correct about the jumper on the ignition. At one point I did think that i could possibly make some type of jumper or adapter harness to plug this in. I don't want to cut up the trucks wire harness. I would consider changing the plugs on the 90 column for the turn signals.
Another bonus is that this column has delay wipers on it. I have all the parts to make this work too. But its another plug that does not match the truck.
