Our standard One-Button Start feature is set for a 1-second fuel pump prime. It is only after that time that the fuel-pump will start to prime. It takes their system 2.5-seconds to boot up. One quick note about the Sniper if you are using our One-Button Start feature. There is no extra fuel pump wiring required to make it work. The rear POWERCELL is mounted near the fuel pump in the tank. The MASTERCELL is located close to the EFI system. ![]() More importantly, having the Infinitybox system control the fuel pump means that you have to run less wire in the car. First, we can disable the fuel pump as a security measure if you have our inLINK Radio upgrade. There are several advantages of using the Infinitybox system to control the fuel pump directly from the Sniper harness. The diagram above will show you how to wire the inVERT Mini between the Sniper EFI harness and your MASTERCELL input. This link will get you more details on the inVERT Mini. You must use an inVERT Mini to flip this 12-volt signal to a ground signal for the MASTERCELL. This is a 12-volt signal so it cannot be directly connected to the MASTERCELL input for the fuel pump.

There are several advantages to using the Infinitybox system to control the cooling fan directly off of the Sniper harness. Check the diagram above for the correct orientation of the stripe on the diode. Note that the orientation of this diode is critical. You must install a diode in series between the MASTERCELL input and the cooling fan trigger on the Holley harness. Next, you need to connect your MASTERCELL input for your cooling fan to the light-blue wire on the Sniper 10-pin harness. This POWERCELL output will supply battery power to the Sniper whenever you have the ignition switch on. In most Infinitybox systems, this is the light-green wire on your front POWERCELL but check your configuration to be sure. Next, you need to bring ignition power from your POWERCELL to the pink wire on their 7-pin harness. Make sure that you have a solid metal-to-metal connection to your chassis with no paint, grease, powder coating or dirt in the way. As we discussed in other blog posts, 90% of all electrical problems relate to a bad ground. The black wire in their 7-pin connector must go to ground. The red wire in their 7-pin connector must go directly to the positive terminal on your battery.
