Why BP Automotive?
Our standalone Vortec harnesses are made with GM color coded TXL wire to meet or exceed OEM standards! All circuits that are near heat like the O2 sensors are covered with 1200* Fiberglass Braid. BP Automotive only uses Delphi, Kostal, Bosch, Molex, and Yazaki products on all of our harnesses, just like an OEM harness. All connectors that have CPA Locks on a factory harness have them on our harnesses as well. Our standalone harnesses also include a sliding, snug fitting Delphi Grommet that can be positioned on the main harness line to seal your firewall.
4.8, 5.3, and 6.0 swap harnesses from BP Automotive are 5 foot long from the rear of the intake! As a result, our customers can mount the PCM and Fuse Block in the passenger compartment! However, if you don’t have room inside your passenger compartment with the 5 foot of length you will have plenty of options in your engine bay as well! The fuse block included has been used on many GM applications and has all of the weather resistant covers! The top cover is even labeled with a legend like a factory GM vehicle. This fuse block design and length gives our customers more options than other standalone harnesses can. Our Drive by Wire Vortec T56 Standalone harness is for pre emissions vehicles and are for off road use only.
Our LS standalone harness assemblies also require the removal of VATS and emissions systems from the PCM. BP Automotive offers this service as well. This LS1 standalone harness also requires the use of a Blue and Green PCM, which can be purchased from BP Automotive.
