These are the two additions I added to my 2007 Tacoma.
The ScanGauge from linearlogis is the greratest thing I know of. It gives you trouble code read out as well as trip info and full digital instrumentation.
All this right off the ODBII port under the steering wheel.
ScanGaugeII - Scan Tool + Digital Gauges + Trip Computers
The Nerf bars are all stainless, and took about 10 minutes per side. No holes to drill and all parts are stainless steel. This is the bracket as well as all the bolts.
I recommend them both.
