PSI SilverTurbo LS Swap OBS Truck Overview 

In this video, we're taking a look at PSI's OBS truck 'Silver Turbo.' This 1993 GMT 400 has a 6.0 litre gen IV engine bolted to a 4L80E transmission with a borg warner turbo for boost and a ton of custom fab work throughout. This truck was completely wired with PSI's 'Builder's Harness' which is a DIY harness system allowing the installer to route the harness and place the ECM and fuse block wherever they'd like in the vehicle, allowing for a cleaner install.
Wire it UP and Fire it UP!
