Black and yellow if I remember correctly.
The fuel pump wire is yel/blk. I would not cut the fuel pump wire but instead cut the main power to the pgm-fi relay which blk/yel. This way the fuel injectors as well as the pump will not operate.
hey thanx for the help;
That sounds like a good idea. I’d be interested in how you did everything if you actually follow through on it. I cut the fuel pump wire and wired a switch to it. Works great. Easy to do.
