9C1 oil pressure switch

Any one know where to get the 'real' police package switch? all i see at the auto part stores are the regular on/off switch not the police package switch that actually reads the oil pressure.

I think this is the one you need. It's a 3 terminal. Rock Auto has two brands. Here's ACD https://www.rockauto.com/en/moreinfo...037483&jsn=488
Summit has it too. https://www.summitracing.com/parts/a...view/year/1995
This one says it's with guage. https://www.rockauto.com/en/moreinfo...sn=487&jsn=487 The first two may be incorrect.

I'm betting more are out there.

This thread should have all the info you need on this sending unit....

https://www.impalassforum.com/vBulle...ender-mod.html

Keep in mind that the only reason to do this is if you ALSO remove the resistor that is described in the thread. If not, there really is no point in doing the mod. Part numbers and how this sensor will affect your gauge reading wil be explained too.

'95 Caprice SS conversion - Bonny Buckets - 96 Column, Shifter and Console - 3.73 Gear and Herter tune - Z/28 Cluster - Blazer OH Console - Green/Pink bushings - Chromed Impala Wheels - Eibach Springs and Bilstein Shocks - Corvette Engine Dress - the list goes on and still more to do...it never ends.

Hey bob, that info is for the civilian Caprice. Check his signature and see he has a 95 9C1. He's putting in an LT1. I still think the last switch I posted will work for him. It states in the description "with guage".
