Some background info...

Car 1 - 2002 Eco Sunfire with Auto Trans (pulled engine and harness. Junked leftovers)
Car 2 - 2000 LD9 Sunfire with Manual Trans

The obvious problem that would lead to the question...I have been unsuccessful in finding a MT Eco harness. If you haven't figured out where I'm going shame on you. Is it possible to splice the manual portion on the LD9 harness into the Eco harness? Would it yield what I'm trying to accomplish?

Do you still have the auto harness from the Eco? If so just use it.

All you gotta do is plug in the vss and I believe the reverse light switch I'm not sure on the light tho. But all you need to do is either just hang the left over connectors out of the way or cut em off.

Alright...that makes it easier. Thanks.

You will need to get the pcm reflashed to a manual eco aswell.
