Take your B58 or S58 build further with the JB4PRO Flex Fuel Add-On Harness—a simple, plug-and-play way to add an ethanol sensor and optional fuel pressure sensor to your JB4PRO setup. Keep your install clean, your wiring organized, and your tune dialed to match every fuel blend in the tank. Why it matters: Plug & Play: Connects directly to your JB4PRO—no cutting or splicing required. Sensor Ready: Supports ethanol and fuel pressure sensors for precise, real-time fueling adjustments. Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware. It’s not a complete flex fuel kit—you still need a compatible ethanol sensor—but it gives your JB4PRO the accurate readings it needs to adjust timing, boost, and fueling for E30, E50, or E85 blends.

Designed specifically to work with the RennStand Jack Stand (18M-RS3), RennStand's new Puck Castle Pad (Patent Pending) will hold a standard NHL hockey puck (not included) and is for those DIYers who prefer to place a hockey puck on their jack saddles to prevent damage to their jacking points. This pad can also be used without the puck, offering a universal castle-style saddle. The Castle Pad is a miniature version of a low-profile jack saddle, meant to allow the RennStand's crossbar to essentially be an extension of your jack, so if you typically lift your vehicle using your jack without any specific pad on its saddle, then this is the pad for you. Now your RennStand gives you the same benefit while you lift and support your vehicle at the factory-designated jacking point
