Hey does anyone have the pin locations for the pcm to plug the add on harness into the pcm for a 98 Trans am (4l60e) I got the wiring diagrams and the connector end view for the pcm but can't find all the locations and the wiring diagrams and pin locations on the connector end view aren't the same on some of them. I am not sure which one to believe. email it to me if you want.
Thanks,
Chris lucyandchris@shaw.ca

here is what I got, maybe someone could double check it.
trans plug.
a goes to pin 35 connector c1
b goes to pin 40 connector c1
c to pin 39 connector c2
d to pin 36 connector c2
e fuse 16
l to pin13 connector c2
m to pin 14 connector c2 ( not sure about this one... the ckt numbers are diff)
n to pin 25 connector c1
p to pin 61 connector c1
r to pin 22 connector c1
s to pin 34 connector c1
t to pin 32 connector c2
u to pin 33 connector c2

C1 77 goes to power from the brake pedal switch. interupts the power signal when the brake is pressed.
C1 32 goes to the neutral park switch at shifter. grounds when shifter in park or neutral.

That looks correct. The only thing I see missing is C1 77 to your brake pedal (unlock TCC)
