The "Original" SAIS Wired Bypass Combo Kit includes a SAIS Bypass Module Kit and a SAIS Pump Replacement Pack.. Click on images for more details!
These kits prevent operation of the secondary air injection system at cold start. By preventing the SAIS from operating many of the trouble codes, CEL and Limp mode that are associated with a SAIS failure will not return once cleared. This wired version of the bypass kit installs very easily by tapping directly into the factory IAT/MAF Sensor harness. Detailed Installation Instructions are easy to follow and include all needed wire colors and an easy to read wire diagram for proper installation. For those that prefer a more professional and discreet looking installation this easy 4 wire hookup allows the bypass kit to look like it belongs in the engine compartment while being more affordable than our Plug In Version.
One SAIS Pump Replacement Pack is needed for each code i.e. if you have a P0418 and a P0419 you would need to install one pack on each Air Pump Driver.
Pump Replacement packs will work on all of the same vehicles as the SAIS Bypass Kits.
A SAIS Bypass Kit must be installed to use a Pump Replacement Pack.
The SAIS Pump Replacement Pack is an Add-On to our popular SAIS Bypass Kits. Normally our SAIS Bypass Kits can’t clear a P0418 or P0419 but now they can with the additional installation of a Pump Replacement Pack. The other option for clearing a P0418/P0419 code after installing a SAIS Bypass kit is to replace the SAIS Air Injection Pump with a new and expensive unit. That is a particularly expensive repair if you have to pay for the labor on a 4.7L engine where the Air Injection Pump is located under the intake manifold. Installing a Pump Replacement pack is much less expensive that having to replace an air injection pump and you can just leave the old faulty unit in place. These packs install at the SAIS Air Pump Driver that is located on the driver's side inner fender well. There is no need to remove or replace the bad air injection pump when installing one of these packs.
The engines with smaller displacement than the 4.7L have only one air pump that can cause a P0418. Depending on year, the 4.7L engine can have one or two air pumps. A P0419 is only possible if you have a second air injection pump. The 5.7L engines all have 2 air injection pumps. For those vehicles with 2 air injection pumps, both air pump drivers will be located back to back on the inner driver’s fender. The Bank 1 Air Pump Driver (P0418) is located towards the rear of the vehicle and the Bank 2 Air Pump Driver (P0419 is located towards the front of the vehicle).
For more information on trouble codes that Can and Cannot be cleared with the bypass kit alone... Please check our Trouble Codes Section here: Trouble Codes and review the installation instructions here: Installation Instructions
The bypass module is activated when the ignition is first switched to "ON" and any time it detects a 4-12V signal on the starter relay wire. The starter relay option is only available on the Original SAIS Bypass Modules! This option, when connected, ensures that the module actively prevents the SAIS from running on EVERY start. With the starter relay wire connected you can turn the ignition to "ON" for any period of time and the module will be active as soon as you crank the engine. Without the starter relay wire connection you would need to turn the ignition back "Off" and then crank the vehicle to ensure the module is active or the system could operate and cause trouble codes and the CEL to come back on. Just install the kit with the starter relay wire connection and don't worry about having to start the engine as soon as you turn the key on! If anyone else drives the vehicle this is a Must!
The included No.2 Exhaust Valve Block-off Plates are an integral part of the bypass kit (images may not match the plates you receive for your specific engine). The block off plates are the only way to isolate the exhaust valves and the related pressure sensor(s) from the exhaust. By completely isolating the system from the exhaust the pressure sensors are prevented from causing valve stuck open trouble codes which are the main cause of limp mode when this system fails. Even though a system is bypass and should never run again, the Exhaust No.2 valves can still leak exhaust and cause future trouble. Installing the block off plates is the only way to prevent future valve trouble and limp mode. Again, it is just best to install and forget about it.
