Why Choose PSI?

Components/Innovation - All PSI harnesses are made with automotive grade TXL/GXL Wire, an Integral Fuse/Relay Center, and GM Delphi components (no foreign knockoffs). Additionally, a Grommet Seal is integrated into the harness for a clean, factory look. The seal allows a 2-in hole to be drilled in the firewall so everything can be routed from under the dash into the engine compartment. The seal can slide on the harness to accomodate various engine positions and then snaps into the hole, it is NOT a split seal. We provide about 4-5 ft of harness from the back of the engine to where the PCM mounts on all harnesses.

Customization - PSI does not ask you to change your combination to fit our harness. We provide harnesses for all GM Gen II, III and IV engine platforms but it doesnt stop there... If you are changing intakes, injectors, MAF Sensors or transmissions to a combination that wasnt available through the factory, we can provide the customization that you need to make it work right!

Quality - EVERY harness is crimped to Delphi Specs using hand or automated tooling and 100% pin to pin tested.

One Stop Shopping - PSI carries a complete line of components to complete your conversion. These include Tuned PCMs, DBW Components, Throttle Bodies, MAF sensors, O2 sensors and much, much, more!

Customer Support - PSI harnesses are IN STOCK and come with complete phone or email tech support. This is something we pride ourselves on as we have found many companies are no longer stocking components or offering the tech support they should because they are trying to keep costs down. We are active on this board because YOU are our customer. Whether you purchase from us, a competitor, or build your own harness; designs and ideas can be shared through this board to make products better. As always, thanks for your interest.

The PSI Team!
