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.

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.
you meen removed from the pcm connector? im not quite following you.Originally Posted by GasGuzzler
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
I mean look for the other end of the wires at the PCM. The data line may be one of the most important wire there is.
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.
