re; those white lights on rear won´t light on when transmission is in R position, what are those lights called?
Those are the Back-Up lights (also called Reverse Lights...); the circuit that turns on the reverse lights is controlled by the Neutral Safety Switch (NSS).
Check basics... pull bilbs and sk.. uses jumpers at battery to tect each bulb; inspect sockets for corrosion; place test light or better, a digital meter at sockers and test for 12v DC at sockets when inreverse w/engine on.. BE CAREFUL!..etc,
Then ckeck voltage at NSS
Some switches have 6 pins... if your's has the 6 pin conn...

"TOUCH DRIVE" - NEW ELECTRONIC CONTROL MODULE FOR 1991
A new electronic control module has been installed on the 1991 model Ford trucks with "Touch Drive," built after 8/6/90. The new module features a different computer logic to control shifting. With the previous module
, it was possible for the driver to select 4L directly from 2WD. However, the control module actually shifted the vehicle into 4H first, then checked to see if the vehicle was stopped and that the automatic transmission was in neutral (or the manual transmission clutch was disengaged). If these conditions were not met, the actual shift wouldn't take place. Instead, everything would be made ready for the moment when the shift could be completed. This was called pre-staging.
During pre-staging, the Low Range light flashed. This confused some customers. In addition, pre-staging and the flashing light sent confusing signals to the new E4OD transmission's electronic controller.
The new module solves both these problems. With the new logic, if the driver selects 4L when in 2WD, nothing will happen, because the transfer case controller ignores the 4L signal. The driver must make the shift to 4H first, then (while stopped) shift to 4L.
