should be 2 big wires black with white stripe (i think), they are for park/neutral safty switch, you can run them to the clutch switch on your new manuel pedals or just connect the 2 together. thats what i did, 88's didnt have clutch switch (at least didnt show it on my 88 helms), do that so you can start your car, then if you want reverse lights there is a yellow wire and a green with black strip wire next to it (again im not sure about colors on yours) but you will need to run them to the reverse switch on your new trans. the rest of the wires you can just leave. i have done the swap on a few ef's its not that hard
