I have a 3g eclipse and a brand new ralli-art engine I want to install. My mechanic said he can install it but he needs the wiring harness for the engine. I have the one that connects to the head. However I called to order the other harness and they told me there are three total. However the guy said that the other one looks like it might be the harness for the lights. the harness go for over 600 each so I want to make sure I only need one more. Other wise I will not install my motor because it will cost to much. So if any one knows please let me know thank you.....
