Took some cropping to get file size down and it still be legible, but here ya go...PM me if you need a copy of this or a schematic of mine for either harness......


From an 05 Silvy....

 

Now the real question.....

Does the pin 33 work on the 03-04 PCM's ????

 

working on that too...hope to know for sure next early week!

 

Guess I can go out test that for you tonight.... It does in the 05... It is just the opposite connector than the Pin 42... I will also pull my helms manual and see what the ECM pinout says .......

 

all done...and yes it does ... w/ HP Tuners you have to have "2 fans" enabled (not "aux fans") but in my '03 Av pin33 works, it was blank, I added a new wire and wammo a second level of control from the pcm. I did some testing w/ the a/c (before the engine warmed up) and the a/c head pressure did not make either pin work. I will be wiring a 4th relay to ground the blue wire (pin 42) when the A/C comes on.

 

Thanks for checking this out.
