Need help identifying these LS plugs

Got a couple of plugs that I can't find a home for on my 5.3 LS ...
I think they might be the ABS pump that was on the frame of the 2000 sierra and or the fuel tank connections.. Any ideas? Thanks

Hard to tell exactly without seeing the wire colors, but if they are on the same branch of the harness, I would say MAF and coolant level sensor.

Re: Need help identifying these LS plugs

I'm pretty sure that purple one is MAF as was stated. The two-prong plug next to it is used in a couple different places, but I'd probably say the guess of coolant level wasnt too far off.
