Default Where the heck did I screw up my T56 swap wiring?

I am totally lost here. I poured through the T56 swap thread for hours trying to make sure I did my wiring right. Read all the posts, the writeups, etc.

My transmission and everything is in the car, bolted up and ready to go.

I did all my wiring and NO START!

And on top of it all, it seems to be draining my battery somewhere.

Haven't driven my car in months, I'm ready to DRIVE THIS THING!

I connected the orange/black wires for the hatch release:


I ran the green/purple wires up to the clutch switch (pic showing which wires I cut and extended) :


I extended the wire for the VSS on the side of the transmission, and I snipped out the brown and light green wires that used to be in the big plug on the 4L60E and attached them to a pigtail for the reverse lights.

For the reverse lockout, I tapped into the blue wire on the brake light switch and ran it down to the connector, and then the other to ground.


WTF is wrong here?

Anyone in the Raleigh area want to come give me a hand? I'll buy the pizza and beer!

Did you account for the Neutral Safety Switch?

You mean the switch on the clutch pedal, right? I wired that up with the green/purple wires in the pic.

Hey Guys, if you have done the swap, PM Bryan with some info.

Bryan- I would do a search through the m6 section.
Look under T56, Or six speed swap as it pulls up different post. if the answer is not there but you found a member who may know the answer. Then PM him.

I did that for m6 cars going TH400.

I found this....
http://www.gmhightechperformance.com.../photo_69.html

http://www.gmhightechperformance.com.../photo_70.html

The car was a M6, converted to A4, and back to an M6.

I did, and I thought I got everything straight. I spent hours pouring through that thread trying to find the way to wire it, and printed out those GMHTP photos to do the wiring.

I'll go back through and see if I missed anything.

I very well may have done everything correctly, but maybe I blew the starter fuse or something. I need to check them to see if they are correct. Who knows, my starter may even have magically died.

All I know is the weather is damn nice and I haven't driven my car all summer long!

Ok here is what you can do..... dig underneath the pass side of the dash and pull out the BCM. The BCM is the black box. Disconnect the big blue plug. find pin C11 its a yellow with a black wire. Cut the wire and ground the harness side of the wire. The wire is the ground to the relay that controls the starter .Hope that helps.

your not getting the signal to ground the starter from the key to the bcm. I have gone through this on a swap. you ground that wire and your golden. it bypasses the bcm so it no longer uses it to start the car. everything else will work perfectly.
