Working on a 1974 F100 with A/T that had no horn, no turn signal return, and hard column shifting. When I removed the steering wheel and grounded the spring loaded post, the horn worked. So maybe a problem in the steering wheel rings.The t/s return problem was obvious, there was nothing there...

My 1986 F250 (460 v8) cruise control engages with sudden acceleration and gains about 3-5mph from the set point.There must be an adjustment for this, just don't know where.Also, should I consider restricting the vacuum source so that it doesn't engage quite so harshly?Thanks!
