I have just found the egr harness info for the truck...thanks to cablebandit

from the gm dvd info on the egr harness,
brown 0-5
grey +5vdc
purple gnd

the pin config. of my sender...
http://shed51.com/sensors.htm
which is the same as the AutoMeter fp sender's configuration:


and the pic of my sender pigtail below,



we have come up with this...
sender/pigtail to egr harness

Blk (gnd) to purple (gnd)

Grey (+5vdc)to grey (+5vdc)

Blue (0-5) to brown (0-5)

thanks for the reply yesterday...
you must've replied as soon as I walked out the door to go to dinner last night...

OK...someone on LS1TECH caught this before you guys...

I was looking at the plug end of the pigtail the same as the sender's pin out, which is incorrect because it is actually a mirror of the sender...

The CORRECT connections are:
sender/pigtail to egr harness

Grey (gnd) to purple (gnd)

Blk (+5vdc)to grey (+5vdc)

Blue (0-5 signal) to brown (0-5 signal)

[Superado]

it works!
and logs!

question...
now that I have the egr reading fp...how do I turn off the SES light due to egr?
thanks
