Simple...If your running an auto such as a Powerglide, TH350 or 400 then just wrap the uneeded connections in case you want to go manual in the future. If a 4L60 and above then either look into getting a harness for your current ECU or invest in an aftermarket one such as the Holley Terminator or Dominator system which will provide you with everything you need to connect to a newer style transmission.

So you have the 411 ECU correct? If so then look for a 98-02 F-body harness for the 4L60E and you're set!
