#PT949-35340-is already instaled-remove it--in PT 949-35240 kit wil be replacement that u need for compressor--most likely u will need to cut hoe for compressor---use door from storage box on passinger side--the rest is all plug and play--no aditional wiring required
I installed PT949-35240 Toyota air comprasor ---total time 2hours including time to cut and fit 1/4 inch reinforce panel on bed side wall, although it is not reuired----compressor itsellf takes 15 minutes, plug and plaay
