When ordering a harness we want to make sure you have exactly what you need. There are several different connectors in use on the GM engines within the same year and engine size so to make absolutely sure you get what you need please email us the following.

1. A picture of the alternator plug in connector.
2. A picture of the front oxygen sensor plug in connector on the engine side.
3. A picture of the injector plug in connector.
4. Verify once more the transmission type, either 4L60e Automatic, 4L80E Automatic, or Manual Trans and if so if it is a 4, 5, or 6 speed.
5. Verify once more Drive by cable (it has a throttle cable) or drive by wire ( it has no throttle cable)

These items are very important to insure you get a harness delivered to you that has the correct connectors on it. If you supply these pictures to us and we send you the incorrect harness we will exchange it at no shipping charge to you.
