Need pic of '95 OBD1 port

The guy I bought my car from said that the PCM and block was from a 95 but the port looks like it's from an earlier model OBD1 and the cable I just bought for the '95 from moates.net does not fit. The previous owner told me that he made his own cable and I'm wondering if he hooked up an older style diagnostic port to make it easier on himself. I just really need to see what a '95 LT1 port looks like so that I can try to figure out what's what.

I just got the cable tonight and I haven't had a chance to look at the PCM but if it's a '95 should it have the 8051 code on it somewhere?

the 95 port looks like an obd2 port but if you look inside of it it actually only has a few prongs

it's the 16 pin

Well, it looks like I have the right cable for a 95 but the wrong PCM or connector. What would be the best way to tell what year the PCM is from?

You probably have a 94 OBD1 Hybrid system but the diagram below will tell you if thats the case but the PCM itself for a 94 and a 95 is exactly the same. The engine itself has a couple differences between a 94 and a 95 though.

Great info guys, thanks a lot. It is a 12 pin connector and going by the picture above only the B, A, and M terminals have pins in them so it seems like maybe it was a custom job. Any idea how I could figure out what's going on?

EDIT: The only reason I'm a little confused is because my car in an auto with a 4l60e, so shouldn't it have the TCC terminal populated?

Everything wiring wise for a 94 and 95 is exactly the same. The terminal are just different but the same exact tranny was used in 94 and 95, They were both 4L60-E's. Do you have wires on the end of your cable or the adapter for a OBD2 terminal?

I have the OBD2 terminal. This is the cable that I have http://www.moates.net/aldu1cabl2-combo-p-128.html.

What you need to do is take two paper clips or jumper wires and have terminal 5 on the cable end go to terminal A on the datalink terminal and have the the other wire or clip go from terminal 9 on the cable end to terminal M on the datalink end. Then it should read and flash correctly.

You want to test the connection with a scan first though using free scanning software beforing you start the flashing and reading programs.

Great, that makes sense. I'll try it out tomorrow and let you know how it goes. Thanks again for all the help.

No problem and let me know if you need some scanning software. I can send you a link to some free stuff to use.

Alright it looks like the cable and paper clips are working, but I'm having a hard time finding a good scan tool. Any suggestions?

I will try to find my disc of freescan DL, If I can find it where do you want me to email it to.

That would be awesome if you could send it to [email protected]. What flashing software would you recommend, I've heard really good things about Tunercat.

I couldn't get the link threw the guys site to work for the DL but I found a old default link threw a site that leads to the page to DL freescan. So here it is http://andywhittaker.com/ECU/FreeScan/tabid/70/Default.aspx

Hmmm..... I can't seem to get FreeScan to work. I double checked my comport to make sure it was right, but nothing seems to be coming through. I also tried DataMaster and it gave me an error saying ALDL converter is working but PCM is not recognized. I took the underdash panel off and tried to get the PCM free to see which one it is, but he put a metal band around it to keep it in place that looks like to pain to get off. I'm just going to e-mail the guy and see if he can well me what he really put in there.

BTW, is there any differance in the size, shape, or color of the PCM to tell which one it is? If so I can take a pic of what I can see of it and post it up, but if they all look pretty much identical I won't bother.

And you're sure you have 5 to A and 9 to M?, Sometimes in Freescan you have to force the connection by switching in the control section to interact mode hit force connection and then hit the start button. Also make sure the default is set to the correct comm port.

If this still falls to read. Get me the serial numbers off the computer cause it could be that you for some reason have a OBD2 PCM.

Yea that's still not working, and he guy hasn't responded yet. I'll send him another e-mail and wait a couple more days before I try to get the damned thing loose. He rigged it up in there in a way where it looks like the only way I'm going to get it out is with really, really tiny fingers or take the dash apart. Hopefully he'll come through and tell me what he put in there and I can get it working.

Alright the guy said that it is a '94 but it has a '95 vented optispark and that was were the confusion was. I guess that my paper clips aren't quite working right, because I did get it to work for about 10 seconds.
