Nope, exactly the same wires, just de-pinned my plug and used the spade connecters off the stock harness and plugged it right in. Worked like a charm.

Hi mate It is a bit late(just about 14 years) but now that I finally fixed my bike i was and am future proving the system, thinking about getting another r&r, you mentioned not rewiring the cables leading to it but in another reply you mentioned replacing it with a 14 gauge. I would love to get some more info on it and do you know if they make any harness adapters for it as I do want the ability to run it back to stock in matters of minutes. Thank you in advance

Hi I need to get the ultimate r/r upgrade for my f4. Looks like I need one with MOSFET technology as above. But my bike has one connector going to my r/r. The MOSFET one pictured has two sockets. What’s the 2nd one for? Do I need to do any wiring mods or purchase different connectors?

Thanks a lot

Default Rewiring modification and/or instructions needed.

So as above my F4 has one connector coming from my loom. It now needs to be spliced to be spread across the 2 connectors going on to my new upgrade r/r as the photo above. But my new one from Ultimate Regulators didn't come with a diagram or any instructions. Does anyone on here have any?

Thank a lot

P.
