DPR reading

[CTDiesel at aol.com]

Ok so after lots of trying i ordered a wiring harness to check the Diff Press
Reg.  I though mine wasnt any good that i made since i couldnt get the
reading.

So i finally got the harness and hook everything up but still a bunch of
erroneous numbers on my mulitmeter.  I cant figure it out with a VW/Audi
harness it cant be a set up problem.

I know the DPR works cause if you unplug it the engine labors.  So can anyone
help.   A couple of you have helped me out in the past with this problem
regarding the harness now i'm not sure.

The mA should fluctate a lot or a little around 10mA at idle right?

TIA,
DJ
