Great. Now that the
plug is all wired, and the harness neatly tied in I learn I need a 5V lead from
the AQM plug pin? It’s a well kept secret; not a clue in the manual.
DOWN WITH SOLDER SOCKET PLUGS!
I agree about
the solder plugs, but you don't have to open up the plug
again. In the bundle outside the EM-2 plug, splice into the wires
that go to the liquid temps, and also a 5V wire. You'll need
a wire from there to ground for one end of the resistors also, but it
can all be done right there at the harness. Imagine how I know this
:-)
Good info, but my
MAP account is as empty as
yours.
Then here's how
you can repay me :-) When you hook this up, you could do me a huge favor,
and test something for me. I only have one of the 3 wire temp sensors,
which is the OAT, so I used that 5V wire for both aux liquid temps as
well. Now that I find my OAT being a bit off, I wondered if I was causing
an error by tying into the 5V line for two other sensors. If you get
to the point of hooking this up to one of your existing air temp 5V
sources, it would be real interesting to know if your temp reading
changes when you connect the liquid sensor circuit. I really doubt this is
the problem, but had already made a mental note to check it if I didn't come up
with some other calibration solution
eventually.
Cheers,
Rusty (need
better inlet)
