#4 is a ground and #16 is battery voltage......so you ran a direct short to your battery, which blew the fuse protecting it.....I am looking at a '96 manual diagram, and terminal 16 is protected by a 10 amp fuse, fuse 9C, in the I/P fuse block.....pretty sure it will be the same for a 1998.....if fuse is blown, replace...
I am not sure if you can program a fob on this vehicle manually or if you need a Tech II scan tool....
If it can be manually done, did you use this procedure? remember, if you have more than one transmitter, must program them all at once.....if one is programmed, and you program a new one, the old one will no longer be programmed....
PROGRAMMING TRANSMITTERS
1. Turn ignition off. Connect fused jumper wire between Data Link Connector (DLC) terminals No. 8 (Black/White wire) and No.
4 (Black wire). Turn ignition on. All door locks will cycle. Press and hold LOCK and UNLOCK buttons of one RKE
transmitter. After a 30 second delay, door locks will cycle.
2. Program any other RKE transmitter to be used by repeating previous step. When all RKE transmitters are programmed, remove
fused jumper wire from DLC connector, before turning ignition off.
