Does anybody know what vehicle came with grey iat sensor plugs, like the holley & MSD sensors. It would be a lot easier to source it from a junk yard then online.

 

Basically all GM IAT sensors from the mid 80's to present use the same connector or a variant of it that still fits

If you're sourcing several connectors for LT1s or LSx, look to vortec S10s. They share about 90% of the connectors for both engine types

 

mine came from a late 90's blazer with the 4.3

 

Thanks for the reply. My tip it won't fit the holley gray sensor. Seems like a lot of cars that I saw at my local scrap yard had maf/iat combo. Nice to know what cars may have the gray plug.
