TESTING # 781 for TRANSPONDER:

When connecting the #781 for the transponder bypass, make sure that the YELLOW/BLACK wire from the #781 is connected to 12v constant and the WHITE wire is connected to the WHITE (thin) 16ga. wire (no other wires on the #781 need to be connected for the TRANSPONDER INSTALLATION) on the 3 pin harness from the relay pack as stated in the manual. The ANTENNA LOOP that is used to transmit the TRANSPONDER key SIGNAL form the #781 to the RECEIVING ANTENNA on the IGNITION SWITCH TUMBLER, comes with 3 LOOPS on the antenna, it is best to have at least 8 LOOPS on this antenna to get a proper signal to the receiver at the tumble..............When placing the TRANSPONDER KEY inside of the GRAY RIBBON CABLE in the #781 module, make sure that the key is placed in-between the cable without any obstructions, the tape that is sent with the units to hold the key in place, should be attached to the lid to press the ribbon cable tightly against the key do not have tape wrapped around the key as this will interfere with signal from the key.

TESTING #781 for TRANSPONDER OUTPUT:

To test the #781, unplug the WHITE plug from the ANTENNA, that plugs into the P.C. board on the inside of the #781 and run a CONTINUITY TEST across both of the wires in the end of the WHITE antenna plug on the antenna, THEY should show CONTINUITY, then test the 2 pins in the plug on the # 781, without the remote starter being activated there should be NO CONTINUITY on the 2 pins, when you activate the remote starter then the 2 pins should show CONTINUITY, press the STOP button, and it should again go away the unit tests fine...........

NOTE**** When connecting the # 781 up to GM's PK 3 (PASSKEY 3) connect the YELLOW/BLACK wire from the #781 to 12v constant and connect the WHITE wire from the # 781 to the YELLOW/BLACK (thin) 16ga. wire on the 3 pin harness on the relay pack AND NOT to the WHITE 16 ga. wire as stated in the manual...........
