I left everything in place and only added the PCS controller. I have the 4 wires located. Clutch switch wires and reverse light wires. I just need confirmation as I called RPM and they use a Auto harness on C5s when doing the swap. I posted this on LS1tech hoping someone can help me out.
For the neutral safety switch the purple and yellow wires from my clutch switch go to C and D based on the connector on the left? But this might be the wrong diagram as I looked on my NSS and it's only 7 wires with 2 of them bigger bigger prongs than the other 5.
Here's the clutch pedal safety switch that I will extend the wires to the NSS
I'm assuming this plug will be where I hook up the reverse light wires? If so which connections and what do does A, B, C and P stand for? Obvious would be P stands for Park?
Reverse light wires
Clutch switch wires
NSS
I've searched and searched with no answers.

For the clutch wire switch you can just make a jumper wire to close the switch and your ignition will work, the only downside would be that you could start the car in gear if not be careful.
Did you install the shifter lock cable that goes from the ignition switch to automatic shifter ?
I'll take a look at the schematics I have on my laptop when I get home. Send me an email at ajg5@aol.com so I can send you over some schematics.
I was thinking of doing this conversion on 2001 SW Z06 as I can't stand driving a stick on the street anymore due to all of the traffic.
I didn't really care for the C6's much and kept the C5 around waiting on the C7's. GM is busy doing a lot of changes with the C7, so I'm kind of in a hold pattern for a bit.
I've gone both ways before however I always went with the GM harness and GM PCM to control the tranny. It wasn't until the C6's came out and they started doing auto conversions on them using the A4's that you started to see guys using the stand alone controllers.

You NSS switch looks different from mine.. I just have one big plug on the NSS switch, not two small ones like yours.. Not sure why its different but... Definitely different.
My PCS harness had the big plug on it for the NSS. Maybe different year models or something..

I got mine from the dealer for a 2003. I hope it's right but I'll make it work if possible.
EDIT: Maybe my PCS harness has it too but I was told by RPM I only needed to connect the TPS, VSS, RPM, Grounds and power to the box.

Whelp I did something right. Shifter bracket is in the correct spot. At first I was pissed because it didn't go through the gears correctly once I got down to 3, 2 and 1. So I was looking how to adjust the cable and removed the red cover and did. Now it works like a charm. If I get it all back together and everything works, I'll work on locating the wires that require the brake pedal to move it out of park.
I've decided to just insert the wires on the NSS terminals for the reverse lights and park/neutral start until I find the right combo, which could take some time. Only sucky part is having to get out from under the car after every combo.

Okay, got the neutral safety switch wired correctly first time around. I switched the wires around to the other terminals to be sure and it wouldn't crank but it would crank if I simply swapped the wires around on the same terminals so I don't know what that means. Posted picture just for someone to use if they want to do the auto swap. I'm going to fill the connector hole with some clear silicon 
I rewired it based on this picture now for the neutral switch and it works

Just checked to see if either the brown or gray wire (reverse lights) have any voltage and nope. Shouldn't one of them have atleast some kind of voltage?
Volt meter was bad and got another one and the brown wire has 12v. Also had to plug in connector for back lights D'OH
Checked #21 fuse in passenger footwell and it was good.
These are the wires I'm trying use for the reverse lights
I connected the wires based on the cut up connector picture above using the brown and gray wires but I have to rotate the Neutral Safety switch so much at an angle (top is at 1'oclock and bottom at 7 o'clock) that the bolt holes don't line up. Anyone have a guess as to why?

For the reverse lights to come on this is how it has to be mounted. If I rotate it anymore towards the mounting holes the lights will not come on for reverse. I know I'm doing something wrong but may just hack it up to mount it like this.

If anyone who did the standalone controller could tell me how exactly they wired up the reverse lights to the switch I'd appreciate it. I'm going to order a new NSS because I beat the one I have up pretty bad. If not, then I may just rig something up for the reverse lights but I really don't want to do that. RPM told me they always use the auto harness for the C5 swap.

I just used the PCS harness that comes with the standalone from RPM.. I don't remember which wire was for the reverse lights. I think the stick tranny had a plug on the side with a wire that actives the reverse lights when in reverse.. I'm sure that tied into the pcs harness that went to the NSS... Like I said, my NSS looks completely different then yours.
I'll look and see if I have any notes laying around from my install. It's been over a year ago I did all that so I forgot most of it. I do know that I did NOT use a GM. Harness at all and I didn't not even tap into the OEM wiring harness.. I just tapped into the 5-6 wires we needed at the switches.

On the 6 spd harness at the tranny, there is an orange plug, that is the reverse light harness. You will have to cut that plug off and run those wires to the NSS... When the shifter is placed in reverse, that selection on the nss will then complete the circuit to the reverse lights and make them come on.
As to which wires that is on YOUR NSS, I can't tell you.
That's all I got man..
Go back to page 1 of this thread and read thru it again. Billy has a lot of info pasted here, it's what I used for my install. My **** works flawlessly. I have over 3k miles on my auto swap now.
