That's why you do it right or don't do it. I can't stand when people do ghetto *** jobs. Anyway, these hacked and spliced MAFs are seeming to become more and more popular with 240s. IDK why, MAFs aren't hard to change at all, a little pricy, but thats about it. My MAF has two grounds spliced into one, then goes into the connector.
Another guy had a wiring problem with his MAF also, I don't have any pics of a good one, but here the link to the thread. I gave which wires were what.
