what computer/throttle system are you using?
if using a cabled throttle body and 99-02 PCM you are good to go.
if using a fly-by-wire (like in 03-07) then it wont work. the serial
data the PCM supplies is "coded" differently.
youll have turn signal indicators (2)
low washer
serial data (oil, water, optional trans temp and fuel) gauges
12volt switched
12 volt constant
ground
driver information center (4)
speedo
tach
MIL
thats all i know of...
