hope the relay and fuse were replaced as well, anyways the best bet is to go to a junk yard or contact a seller on ebay that is selling parts off a gl and ask them if they can cut the plugs for you and ship them to you, then just cut yours off and replace with good ones, wires should be soldered and heat shrink tube used to waterproof, think there are 4 total wires to the compressor, 2 plugs (connectors), 2 larger wires for power and 2 smaller from airmatic computer to tell it to turn on. make sure to verify the used plugs have no damage from heat and waterproofing yellow seal is intact, (where it plugs into compressor), and to cut it as long as they can, 6 to 12 inches, that way you can cut yours back a bit away from where the plugs melted. hope this helps...

make sure the battery is disconnected when replacing plugs...
