You need to host the pic for it to show. Look at the link at the top of this page for forum hosting.
Where did the harness come from? There was no connector? They were just cut off?
what engine, year model, car, truck or van, throttle body style is that harness for?
You had the VATS turned off in the PCM by whom?
2004 yukon i was told denali but apparently they didnt come with 5.3s vats was removed by a guy on ebay (jeff roberts at autocomputertech) who also did the harness.
Uh oh.
Go back and look at the schematics I posted and see if there any comonalities between the wire colors there and the wire colors you have.
the brown/white is the same no others

See if you can match the colors to these schematics for the PCM. A test light or multimeter can help you verify the circuit. Red connector would be your green one.
When I was researching the efan stuff I found out the 99-2002 had different pinouts than the 2003+.
Very few differences. THe electric fan vs. the climate control door control is one and then the TAC module/TB control wiring. Most of the others are the same.
yellow is pin 59 blue wich says unused
brwn/wht is pin 46 green mil control?
wht is pin 10 green engine speed signal
blue is blue pin 17 transmission fluid pressure switch signal b
grenn/wht is green oin 50 vss signal
purple is blue pin 33 tcc brake switch signal
White would be your tach signal. Green/white is speedometer. Brown/white would be a ground for a lightbulb to illuminate a malfunction indicator lamp.
Are those wires broken from the PCM as well? If so, you've probably found the problem. If not...they go somewhere else.
i found an 04 pin out the yellow comes ups class 2 serial data circuit number 710 the others stay the same are any of these needed to start
you meen removed from the pcm connector? im not quite following you.Quote:

o yah there hooked up there where should the unused end go?
for the electric fans make sure you hook it to the light green or may have white stripe and not the dark green. This will cause the DBW not to work.
Without seeing it in person AND knowing exactly what the harness came out of, it would be difficult to say much more.
i guess i might have to send it to nelson and have them take a look the harness
:(
Where are you located?
dayton maryland its right between baltimore and dc
Whoops. I wish I could help more....
Drive it over to the house tomorrow morning and I'll help you figure it out. :laugh:
if i push it i could prolly get there in a month its downhill to texas right?
