Thank you all for your replies. I never thought my first write-up would be worth anything. It was SCARY as ALL HELL to even consider pulling wires out of the PCM (because if something went bad, I would be screwed). But after I did it, it was pretty easy, and cheap!

Nice writeup! I am contemplating getting LTs and this will definitely help if I do, since I am not using my rear O2's at all!

Awesome write up. I got a set of BBK's in my garage I am going to install this week. I will give this a shot. I was going to cut and splice, not now.

You really dont want to cut and splice because the 02 sensors are very sensitive to volateg so the minute amount that will obscured by the connection may mess up the o2. either do this, buy some vette sensors or get extensions

Corvette O2's I can see yes.
But IMHO, the splicing/adding wire length method vs extensions with two added conectors is negligible in resistance value.
The extensions may actually in fact add more resitance than splicing in extra wire.
Thats why I feel like the OP's write up is so good, it's the best possible solution IMHO.

i did this tonight worked perfect! the hardest thing was plugging in the driver side o2 sensor to rear plug. i had both rear plugs next to the trans on the pass side so i had to run one back over the trans. It was all really simple. THANKS for the knowledge!@!!

I just did this tonight, for my new TSP Stainless headers.....

Here's what I did. Please tell me I got it right.

I plugged 25 wire into 28 port, and 28 wire to 25 port
26 wire Into 29 port, and 29 wire into 26 port

65 wire into 68 port, 66 wire into 69 port

68 wire plugged into 65 port, and 69 wire into 66 port.

This is for a 2001 Camaro SS

**EDIT** I didn't delete this post, but what I posted up there was WRONG!! 12-Jul-2012

I drove the car for a while today... Nothing like the smell of cooking new gaskets and anti-seize!

Really afraid to get on it hard though till I know I'm right.

For having a '98, that looks good to me. It's pretty hard to mess up.

I really didn't like the pinout sheets I posted, so I went back and just changed them to some better links.

Try this one http://www.ls2.com/boggs/torques/98pinpcm.htm

The pictures Trans Am VS VR-4 posted really explain it well. Once you get the cover off and see what you're working with it makes a lot more sense. Give it a shot and if you have questions ask from there.

You have the numbers right, just switch them on the blue PCM connector.
