88FC-RE

Im having trouble with my swap and am starting to think that maybe Microtech sent me the wrong computer. I have a 96 13B-re. For the computer i believe they sent me a stand alone for a series 6 motor. When it comes down to the tps wires and everything....the setup is identical to the 20b with my motor. Would i need a stand alone for a 20b even tho i dont have 3 rotors? I cant really figure out my problem so im thinkin maybe i was just sent the completely wrong computer. Thanks
