hi i am new to this forum. . . ok heres my problem i just dropped in the new motor (T2 S5) into my N/A S5 and i noticed that the harness that connects to the strater on the trans is different from the n/a version. i was thinking about cutting up the jdm harness and customizing it but i don't know if that is wise. so i need some advice about how to do this.

If you are worried about cutting up the new harness just make a short pigtail connector to go between the starter and the JDM harness. Once you are certain it works correct it will not be as scary to cut the harness.

i went throught this problem on my s4 and what i did was swap harnesses to usdm, it was a pain in the ass but then i knew evertyhing was right tho

hey i actually have another question, its starting to rain in my area and i am almost finished swaping the JDM T2 in my car but the jdm harness doesn't have the plug for the windshield wipers, is there any way i can fix this problem?????

Use the ones from the old harness. If I remember they are quite easy to remove. Almost impossible to make a mistake.
