I read the post were Jay says to just do a continuity test but my mult-tester is missing again. Besides I'm thinking that since Jay has already done this mod to a M103 car, he can just tell me which wires to solder the resistor to! Come-on Jay, help me out! We've got another track day coming up in a few days and I'm ready to try your mod at the track!! Some pictures would be really helpful too! Please help!
