Does anyone know if there are any other 4 wire relays in the RH rad support/charcoal canister area other than the MAF relay on the 2.8?? There is also a 6 wire isolation relay for the headlights but any other 4 wire ones?

The reason I ask is that I think I am looking at the MAF relay but the wire colours don't match that in the GM manual. Can't remember all the colours on this relay but one is yellow and I think one is red.

thanks.
