20 Manual transmission wiring Before installing the manual transmission you need to make
sure the neutral, reverse, 4x4 high and 4x4 low switches are in
working order.
1. To test the reverse switch simply put the transmission in reverse and
check continuity, any other position should not have continuity.
2. To test the neutral switch leave the transmission in neutral and test
for continuity, any other position should not have continuity.
3. To test the 4x4high put the transfer case in 4x4 high and test for
continuity, any other position should not have continuity.
4. To test the 4x4 low put the transfer case in 4x4 low and test the
switch for continuity, any other position should not have continuity.
Once you have tested all of the applicable switches
install new wires to the existing plugs as indicated below.
1. On the automatic transmission split the wiring loom apart starting
at the connections end.
2. Separate each wiring bundle from the others.

3. The transmission position switch and its wiring harness is the device
you will need to remove from the automatic. 8mm bolts attach
the automatic transmission position switch. (Fig. 4.2)
The automatic position switch consists of 9 wires and two
plugs. The two large wires which are colored brown and
black go to their own plug. The rest of the wires go to another
plug.
