I have some troubles with the MAF's ground conector.
I don't have signal of ground in the conector that plugs in the MAF.

Please I need the Wiring diagram of the MAF in order to know from where comes the ground cable.

If I plug another ground in the MAF conector it works, but I don´t know if the original ground wire of the MAF conector is just a ground reference, or if it comes frome a diode or a fuse.

Your help will be glorious appreciated.
