Ok dunno if this question has been asked b4 but when cutting the wires to the ecu following the http://www.frsport.com/sr20det-swap-engine-harness-wiring-guide-sr20-p-665.html instructions. will the unused wires affect my stereo/heater and fan/ any other electronics. i guess wha im asking is wha do the unused wires in the instructions do?

All of the un-used wire don’t worry about them.
