What do these wires go to? I unplugged them from the inside the cab and pulled them through the firewall with the block but haven't had time to trace them down, does anyone know if they go to the A/C controls? I have a 98 truck dealer manual but didn't see the firewall and cab connectors. This is one reason I need a picture of the firewall plug for the 2002 T/A to compare wiring on my 97.
Thanks

Not too sure if my 93 would be the same wiring as your 97 or not. Some go to the low pressure switch on the accumulator, the fuel pump relay, the automatic transmission plug, the anti-lock brakes and the cruise control as far as I remember.
