92 Vacuum Cruise Circuit (same as '80-91, except VSS instead of PSOM)
IF THE IMAGE IS TOO SMALL, click it.



ERRORS:
1) the PSOM is on the same side of the cowl panel as the amplifier
2) the slip ring for the switches goes to the 2nd terminal up the outer row (not the 3rd) to circuit 511/511A LG
3) not show, but critical for operation, is that 511 LG branches in the turn/hazard switch harness between Connector Y & the slip ring to also feed the brake input to the turn switch for the rear bulbs. The circuit to these bulbs MUST show less than 10 Ohms for the cruise to engage. If LED taillights are installed without a bypass resistor, the cruise will detect their high resistance as an open circuit, and disable, just as if the clutch switch is depressed.


All earlier with factory cruise are similar, but use a cable- (up to '86) or gear-driven VSS where this diagram shows "PSOM".
