What happened to the original posts?

It seems like the guy who originally started this post is the only one that knows exactly what was needed to be done, and all I've seen is a couple of pictures.

I have already installed the Navigation antenna in the proper location under windshield dash pad and added a green wire to the units C2 connector for the VSS signal.

I mistakingly thought I could splice the other end of the VSS green wire to the Instrument cluster connector, but do not see a green wire on that connector. I assumed I could do that because of past experience with Silverado trucks and that being the case..

plug in nav wire and then the factory plugs and it should work. make sure it is a non lux radio or it will not work. no splicing anywhere.

I've worked with GM Navigation radios and Silverado pickups since around 2004 and my first mod was installing a Escalade Nav radio along with a Hummer Bose amp into a 2003 Silverado that came with the Bose sound option factory installed. That mod took lots of rewiring and time and not something I would recommend for most anyone to do.

I have the original Saturn Relay C1 and C2 connectors with pigtails and compared those to my existing connectors and the main difference is the C2 connector wiring, and the main thing is the lack of the VSS signal wire on my Uplander which is what I want to add.

So I asked where can I tap the other end of the VSS signal wire to? Right now I'm thinking the BCM module?
