yes you can... you will need an sr5 cluster from a 4cyl
the hookups are there, but you will need to run your own tach wire to the tach, it isnt hard, there is actually i diagnostic test port for this on the igniter....
since the sr5 and regular trucks used different oil sensors, you will also need one of those... in the std truck it uses an oil sensor for an idiot light... in the sr5 it uses an actual sensor to run a oil pressure gauge.....
