I want to put a 90-92 style dash in my 89 RS. My question regards where the main dash harness plugs into the bulkhead on the driver side of the firewall. Will the 90-92 harness plug right in to the bulkead on my 89, or does the harness need to be repinned?

I would really appreciate some insight here, as my searches havent come up witha definitive answer.

Thanks in adavance.

 

Here is connector C207 from a 89 camaro, I will try to find the diagram I have of a 92 camaro connector.

 

The connections on the firewall *should* be the same. The block which is bolted to the firewall and protrudes through into the engine compartment is all part of the underdash harness.
