Anybody replaced/fixed the MAF sensor connector harness?

I've been having some Mass Air Flow related issues, and I believe it's the wiring going to it. I've asked some more general MAF questions in the general 996 forum, and Loren and others were helpful. But, I can't find any info anywhere on replacing or fixing these connectors.

Has anybody attempted this? Was anybody successful at getting to the connection on this this for testing?

I called the dealer this morning about a replacement MAF connector. The guy said they only sell the whole wiring harness for the whole ECU for $2000. Well, I obviously don't want to do that.

Oh, also I've cleaned it and checked for vacuum leaks and just about everything else.

Thanks in advance..

It would depend on where the wiring problem is. Have you narrowed it down? Have you tried a new MAF to be sure it is the wiring?

A new MAF sensor is on the way. Will probably be here in a few days.

I believe the problem is within the last foot of the MAF wires or the connector. I'm just hoping someone knows a way of non-destructively removing each pin from the connector or has a tip for non-destructively tapping the connections to the MAF and the connector.

Ok, just to let anybody interested know, I ended up taking the smallest sewing needles I had in the house and pushed them straight through the wires of interest. I hooked these up to my DataQ data acquisition module (very cheap and easy-to-use, $25 for four analog inputs). I found that the MAF out was sending a steady 1.35V and did not vary with load/revving the engine. The temperature output did output plausible numbers. I don't remember exactly what the voltage was, but it rose slowly while sitting there and the engine warmed up.

So now I think the MAF sensor is just flat broken. It doesn't look like it's putting out a signal.
