This relay incorporates a 5 second delay for the front axle to engage in order to allow the transfer case synchronizer to energize.
For 88-93 vehicles, if the axle has to be replaced, use jumper harness P/N 15313272. CKT 1695 (BLK/WHT) fits into cavity A of the fast
actuator. The circuit includes the cable seal and the terminal pin. This circuit plugs into the 5-pin axle actuator connector.
