anyone have FSM for a 86 D-150 and can shoot a copy of the wiper motor with delay wiring.

I have an 83 - 84 FSM,, the pick a part parts I had gathered to add delay to the wipers on my 83 D -150 were from a 86,,
between 83 and 86
* the wiper switch is different
* the wiper motor is different
* the main under dash delay control module is the same

in 83 the power to the wiper switch came directly from the ignition on circuit, the wiper switch has an internal circuit breaker, there is also a second delay module in the motor and additional wire to that module in the the motor. (5 wires)
in 86, which I think is when delay wipers became standard the power to the wiper switch came in from the fuse panel. No separate motor delay wire. ( 4 wire)

to make a long story short, I found a D-150 83 that had delay wipers, so my life just got easy,, however I have a set of 86 D-150 wiper delay components and when I bench wire them up, I can get low speed and high speed, but in delay mode instead of the wipers delaying,, they just go real slow,, trying to figure out what is wrong.

thanks
