I'm looking at doing my N2O install here in the next few weeks and am pre-planning my attack strategy. I did a search and found out about the passenger side floor drain plug, and I've found a hole about the size of a quarter in the firewall, between the motor and brake master cylinder (don't know whether it's usable). Anyways, I plan on putting the bottle in the cargo area and will have to run some wiring for AFR monitoring system, plus the typical power/control wiring. I'm using the gauge pod controller from Nitrous Outlet, plus a gauge pod switch center so alot of my wiring will be coming from the drivers side A-pillar.

Any other access points through the truck's body that you guy's know about before I start making holes? Thanks.

Are you referring to the access behind the behind the accelerator pedal? It is plugged with a sealed rubber grommet type plug.

There's also a access hole on the far left side above the brake pedal...
