jhunsch 20 #1 Posted May 5, 2016 Help please. I need to get rid of the smart box. I have been told to get some different ignition coils.. Currently the coils have two wires coming off them / or going to them. Plus the plug wire. I am told do change them for a single wire coil. Plus the plug wire. I understand a single wire coil does not need to receive 12 volt power to function, and I can then remove the smart box. I am also told most all the kohler coils are the same (interchangeable). Two wire and one wire. Anyone know a part Number for these coils. Also know as RedTop coil. Thanks in advance. Share this post Link to post Share on other sites
