I just seen what richp was talking about in the FSM here it is
(1) Disengage wire connector from clutch interlock
safety switch, located under the instrument panel
next to the 100-way connector (Fig. 1).
(2) Locate open by-pass connector, located next to
the 100-way connector.
(3) Engage clutch interlock switch harness connector
into by-pass connector (Fig. 1).
Reverse the preceding procedure to activate the
Clutch Interlock Safety Switch.
