I bought a conversion kit to make my Vette flex-fuel and it came with the fuel injector power/trigger wire in the pin opposite the release clip. The car wouldn't start. My 2007 Vette has the power/trigger wire in the pin adjacent to the release clip...which the conversion kit supplier says was in "reverse polarity," something they had never seen. They sent me another kit with the different wiring and that kit works great. Are fuel injectors on Vettes usually wired this way (reverse polarity), or is mine an odd-ball?
