ta da, im here. the 5901 will work fine in this car AS LONG AS IT IS INSTALLED CORRECTLY, i have the 5701 (same systems except the remote is bigger and has longer range than mine). the PATS thing should be no problem for best buy, since they are a DEI retailer they have all the cool new bypasses that dont need a key hidden under the dash (XK04 or PKall)however if not wired correctly, they will keep the car from starting. I used the same DEI software BB does (Dierctwire) and there are no wire connections that would be made that would cause those problems (unless of course they tapped the wrong wire) the door trigers are normaly closed (the oppisite of what the viper needs to see) so the trigger wires should be tapped into the dome light (actually the light under the drivers side dash) the trunk wire should be tapped into the trunk light.the lock wires do tap in to the DDM (Drivers Door Module) however if they didnt know what they were doing then who knows what they might have dammaged. take it back to them and have them check it out they may have forgotten to plug back in a harness to something (maybe the FEM). if they cant fix it up right, then you take it to a dealer and have it fixed then go back to that store and have them fill out a damage claim (they are insured, so the insurrance company will pay for all the repairs as long as the dealer says that the dammage was caused by their install)
oh yeh, why the f%ck could they not get the starter to work, its a ford, they dont get much easier than this
