I have a 97 Cav, 2.2 5spd. The Motor came from a 99 Grand Am ( I believe GT) 3400. That would be useful too. If you have them. I guess i'll have to fight with it for a while.
shooff@woh.rr.com is my email.
Problem i've run into before with matching the wires by color is the fact that there are times when you might have 2 blue wires for example. Several wires of the same color. But I guess what's going into the firewall block, is likely just the PCM's output lines. Anything that's an Input would run from the PCM to the Engine.
I know what your talking about. The gam harness, I have 6 wires left to figure out and they are the same colors too. Let me look in to some things tonight and ill see what I can figure out. Ill send you the diag tomorrow or monday.

the connector that you were talking about says its different in my computer. I have a 38 pin and you have an eight pin. Is this right?

I know of no 8 pin connectors on my car, no.
So you have the big 38 pin, half of it is grey and the other half is black? Ill email you the engine diagram for the 2.2. maybe you can figure out which ones are left.

GOOD NEWS
The computers data lines can be connected! It works great. I took the engine, wired it all up (on an engine stand) with the harness for the 3.4. I Installed the computer and hooked my scanner up to the diagnostic port that I installed on the engine harness. I had a couple of wires that I missed and had to put power to but I got the scanner to read the engine first. Then I made jumpers to the diagnostic port of the cav. Unplugged th 2.2 computer and turned on the key. When I got into the scanner , to my amazement I was able to access everything wit no problems whatso ever. This is great news for this swap!!!!!!!!!!!!!!!!!!!
If no one knew if this worked, how do you guys have access to the engine computer diagnostics or even know if an engine code has been set?

The grand am harness wiring is only for 00 and 01. so I am told.

Joe, how long til you get that thing in and started? I'm curious as to see how the anti theft system will react.
i had an 01 gagt i wouldn't suggest using that year because you have to ensure that the bcm and pcm are programmed with the same vin. I know this because my bcm went out and to the tune of 1300 dollars for new locks and reprogramming
Check out my page.

The bcm is where the theft system is, the mileage and lots of unnecessary stuff is. Im not too worried about that. Im not changing the bcm. Then again Who knows what will happen. When I jumpered the computers together as i wrote earlier, everything looked good, the theft light didnt blink, and when I reconnected the 2.2 computer it started right up. We'll see in a month and a half.
Well I was hoping to get it in there within the next week. Not going to happen. The car is a salvage title vehice and has to be reinspected. Yeah with the 2.2. Im almost positive they will not pass the car with the 3.4 in there. Ohio sucks in that way. Any way the inspection isnt till mid july so im on hold till then. When I make some progress, You guys will be the first to know.

Hello everyone as everyone knows I have had to work on my car outside and not in the garage ( to much junk to get it in ) . Anyway I get to work on it when I have time and some spare money . Had some extra money and will be moving the battery to the trunk . The intake I have for the engine sets where the battery once was .
Anyway last week I screwed myself when I had the laptop hooked up to the TEC3 . While I was updating the firmware my battery died . That made the TEC3 lockup , and today I sent it off to Electromotive to be unlocked and have the new firmware installed .
I also had to pick up a new starter for the engine . This one is the right starter for the engine , and with the new batery installed the engine really turns over now . I am figuring by the end of next week I should have the computer back and in the car . I still have to drop the tank and install the fuel level sending unit . The aftermarket gauges can't use the stock 60/240 OHM sender . Had to find one that was 0/90 OHM's which came from a 96 J-body .
I may be removing the A/C from the car because I don't really use it . That should shave around 30 pounds off the total weightof the car . If I can there will be more removed from the car . But it will still have to look good afterwards .
Until next time

hey robert any updated pictures?
Opening Soon Kustom J's
The only update I have is on the TEC3 . I had sent it in to have Electromotive unlock it and install the newer firmware . While they had it they also checked it over and found that the IAC driver was shot . Also that the processor was acting funny . They have fixed both problems and said that everything is working great now . Now I am waiting for it to get back so I can install it back into the car .
Thinking back it could have been my problem the whole time . That is if the processor was not working right the engine most likely would not have started ???? Anyway they checked it after changing the processor and said it's working .

Nice....... hopefully you can get that thing out for a drive. Cuz it's sooooo nice.
so joe are you saying that grand am and sunfire haves the same data signal of 4000?
Opening Soon Kustom J's
Uhm....... data signal of 4000? ROFL. 4000 is the PPM of the VSS.
Anyways..... since you're so interested, I am too. What's the updates, and updated pics on your swap?
The 4000 thing is above my head, Im guessing that VSS is the vehicle speed sensor. Thats in the PCM of the Gam that Im using. Im using the PCM of the gam, and every thing else from the cav. What Im saying is that the 01 gam and 01 cav computer systems will mesh together. Now the theft system is the next question, then the tach. When I did the test I couldnt start or crank the 3.4, only power it up. It was on an engine stand. The cav guage cluster didnt show any conflicts yet, the theft code didnt set, and I could access back and fourth through the computers with the scanner to see the live data.
The vin # cant be an issue either because when I did this test there were 3 vin's involved. 1 from the engine donor(gam), one of the PCM(aztec) and one of the cav. I put in the vin of the engine donor in the scanner, found the PCM donor and its from an Aztec. So I really dont think that the stuff that I was told about the BCM and PCM vins not matching will cause conflicts. It doesnt appear to be true at all.
As far as updates on the swap, Im at a stand still right now with the stock cav and lots of parts. I cant do anything till mid july, because it has to get inspected for a salvage title first. Then I can tear into it.
Do you guys think that I should use the cav 4spd auto or the Gam 4spd auto, I can make either one to work, the diff is going to be the gear ratio.
01 cav w/01 3400 gam gt 4t45e
Joe - I'm pretty sure that the swap wont allow your tach to work without some sort of adapter. Though the only reference I have is the video of an L67 swap into a 3rd gen cav. If the 60 degree uses the same CPS as the 2.2 and the 90 degree doesnt, then that might cause it.
As far as the VIN's, I think it was more of an issue that was thought to be with the anti-theft system. Or at the least, the problem may not show when it's all connected, but as soon as you start running the engine it would. Also, the mechanical component (The Engine) would have no way of sending the VIN of the origional vehicle to the PCM or BCM, so really there was only 2 VIN's involved.
Personally, I would go with the trans from the Cavalier. Both the 4t40 and 4t45 are pretty much the same. You can even look them up as 4t40/45 (i saw it posted) Both transmissions are rated at the same max. input TQ (325 ft/lbs) Well more than the stock 3x00 makes. But the 4T40 has a higher max shift speed than the 45 (6500rpm as opposed to 5800rpm) So if you'd ever get into turning up the rev limit's you'd be better off there.
On the other hand, I'm thinking that if you dont use the GA's 4spd, that the PCM will quickly figure out the fact that the gear ratios are incorrect. And possibly throw some codes at you. Since it's expecting to see certain RPM's and such (which should be in the PCM's shift logic). You may also see a reduction in MPG. I know at ~60mph a J-body will turn about 2300rpm's in top gear. (When caravaning to the bash I noticed that when they wanted 55mph, they'd say "2000rpm" I assumed that was for the Canadin folks who didnt go by MPH much, and all the cars are geared the same to be that way)
Today at around 9:20 this morning the Cavy breathed it first breaths in about 2 1/2 years . They were short breaths but the engine did fire and run . No exhaust ??? Very Loud . Even the contractors working on the house stopped to see what beast was making that noise .
Now it is time to tune the TEC3 so it will idle . Baby steps first then watch it run . Once everything is close I will take her out and see what its like having more horsepower than my Eclipse GT , and also being a lighter car by about 400 to 500 pounds .
Oh yeah I already creamed my pants when it fired for that short time .
<a href="http://users.adelphia.net/~rdbryant1/index.html.html"><img src="http://registry.gmenthusiast.com/images/mrgoodwrench/personal_pic.jpg" border=4></a>
Got the engine to idle . Got a few slight problems that will get taken care of . Big one is the cooling fan did'nt turn on and started over heating .
Can't seem to find the radiator cap either . It was on the car , and after I though it had cooled I turned it a little to relieve some pressure . I stepped back and the next thing I know the cap disappears with a geyser in it's place . I have looked all around the car and in a 20' area of the car ???
Looks like I will be picking up a new cap for the car . Also working on the cooling fan problem .
When the cap came off that was the fastest I had moved in several months . They say when something bad happens it goes in slow motion . Thank God that gave me more time to get the hell out of the way .

hey robert u got msn or yahoo messenger?
Opening Soon Kustom J's
Robert, did you check under the car? Or around the engine bay to a place it may have fallen under the motor? If you still have a hood on it (i'm assuming you do) I figure it probably just shot up and hit the hood and came back down.
All the power you have on tap may get a tad annoying. Sometimes from about a 30-35mph or somewhere in that area (no speedo) if I hammer on the gas from 2nd gear one of the front tires start spinning. First time it happened I wasnt sure if it was wheelspin, or my clutch slipping. Luckily, it was just tire.
