2000 Blazer Auto Dim Mirror

Hi I have a Blazer without the Auto Dim Mirror. I was thinking about putting an OEM Auto Dim on. It sounds like the OEM one has a 5 pin connector. Does anyone know if the connector is already there in the headliner?

Thanks, Mike

no its not belive me i torn the head liner out of alot of them theres just one wire if you have the map lights iif your mirror has no power ops then you have no wires
