Need 1998 S-10 4.3 PCM Pinout

[GAMEOVER]

Gonna try out the 0411 PCM with my S-10. Can someone share the pinout for a 1998 s-10 4.3 V6 Big Black Box PCM.....:grin:

[GAMEOVER]

So, can I use a V8 pinout?

[Lextech]

Give me your E-Mail address and I will send you the wiring file.

Why not post it?

[Lextech]

Why not post it?
That is a very good question. I have given out 3 V-6 Black Box to 12200411 PCM wiring files and NOONE gotten back to me on the "Correctness" of the file. I don't want it posted until it is verified as correct. I am not a GM tech or a business, just a guy who likes to mess around in the garage when I get home from work when I get the chance. I really don't want to post up something that is unverified.

Jeff

Ahh.
I thought you meant the Black Box's pinout.
If the Black Boxes are all the same like the 411's are it should be easy.

I may be mistaken, but I don't think Jeff has a v6 to verify anything on. so thats why he's looking for some feedback on his wiring file. its strange with the blackboxes too, because they were some of the first OBDII PCM's there were alot of changes year to year, even mid-year changes. so its not as cut and dry as the 411.

I can do a Mitchell wiring printout and scan it to a pdf if that would help.

[GAMEOVER]

That would be cool!

I'll try to get done this weekend.
I can print out today at shop, and try to scan tomorrow at home.

I am one of those that you gave the diagram to. I am double checking it right now with a print out a buddy got me from all data for an 01' S10. The printout he gave me shows PCM 12191110, not 0411 like the 01' should be. First I thought it must be a 4 cylinder diagram, but it shows 5 and 6 injector controls. I'll try and let you know what I find out about the pinouts matching.

[scuzz]

That would be cool!

My PC with the scanner took a dump last night and I've got to get another motherboard.
If you want me to mail pinout to you, PM me address, and I'll get it out in the morning.
It might be a couple days before I get board changed.
I've been gone to convention all last week, and will be covered up this week.

I can probably pull the diags off TechLine if anyone wants to double check them from there too.

[Lextech]

I have been out of town. All of my wiring info is at home. I let "Gameover" know I wouldn't be able to send him the wiring file until Tuesday (2 more days) He WILL get the file on Tuesday.

Jeff

I hope these 4 pages get to message.
I got PC back up tonight, but couldn't get scanner to combine all 4 pages into one pdf.

Sorry Jeff if I dropped the ball, I thought we had validated my '96 4.3 to '0411 but not on here. I will thank you once again....actually a MILLION for your help and time that you have spent. If you need anything, I will be back in the states after Nov 3, 09 where my files and your spreadsheets are located. The 96, 97, and 98 seem to have small differences from what we were experiencing. I will be more than happy to help out in verifying your pinnouts where I can.

I drove on the conversion accross 5 states for 1,500 miles with great results...just have the KS code and will swap out the sensor as the '96 type needs to be swapped for the '01 type. It should run better still after that.

I'm coming back to finish up my project and install the marine manifold and Procharger S/C w/ intercooler in the month that I'll be back.

Good times!

Bruce

[Lextech]

There are 3 different V-6 S10 versions that I have. I Emailed "Gameover" the 98 version this afternoon.

Jeff

[Lextech]

Hey Bruce,
You didn't drop the ball. You helped out with good feedback on the 96 file. The 96 S10 file should be correct. I don't think I have given out a file for the 97 S10. This is the 4th 98-2000 S10 file to be given out.
I think it is correct, but "Gameover" is proofing it when he does his PCM swap.

Jeff

[GAMEOVER]

Jeff,
I finally finished up the PCM swap and everything was perfect, all wiring & info was exact match...:thumb_yello: Truck started right up, no problems....
Ill have time tomorrow to do AutoVE and play with it somemore....

Many thanks Jeff!!!...:D:D:D

Let me know if you need any feedback from me...

[joecar]

Good job...:cheers:

The only thing that I'm having trouble with is controlling my E-Fans. They will not turn off.... They stay on at startup... Same problem I'm having in this thread with a 2000 Silverado that I added E-fans to....:http://forum.efilive.com/showthread.php?t=12607

[GAMEOVER]

I think is has to do with the EGR, or AC... Something in the PCM or tune is turning ON(triggering fan relay) the fans at start-up... IDK...:confused:

[GAMEOVER]

Well I give up on this PCM controlling the e-fan.... I've never had a problem when swapping LS motors into different vehicles, fans always turn On & OFF like they should...
Controlling the e-fan's is only for motor swaps...:)

thats nuts man. I don't know what to tell you. mine doesn't have any issues and I'm not running an LS motor. I guess you could just get a fan controller and forget using the PCM.

Are you running egr, air pump or any emissions equipment thru the PCM? I think one of those might be my problem...

[GAMEOVER]

Every other time that the E-fan's worked properly thru the PCM was when I removed all emission and AC wiring from the PCM

[Aloicious]

Are you running egr, air pump or any emissions equipment thru the PCM? I think one of those might be my problem...

yeah I ran EGR for a while with it. not currently but I have ran it with the efan on before. I don't have an AIR pump so that may be something.

[Aloicious]

I did find something with your AC control settings that may be causing the problem though...at least from looking at your posted 2000 silverado tune.

try changing {G0106} from "auto recirculation" to "fan #2 control"

that is a dual purpose A/C and fan controled pin.

[GAMEOVER]

Yeah I already tried, on the 2000 Silverado & my S-10, tried setting to "fan #2 control" and then set to "auto recirculation" neither setting's made a difference... I'm gonna remove the pins for the EGR, Air Pump & AC one by one to & check & see if one of those is causing the problem...

[GAMEOVER]

Yes I finally got it to work...:) I had to disable EGR, Air Pump, All EVAP System and I had to disable all AC inputs(physically removing pins from PCM and changing DTC enablers to "NOT REPORTED"... Now I have to find out which input or input's were causing the problem!!!

its something on those circuits. good job, just gotta narrow it down now :grin:.

I'd venture a guess at the Air pump. I've had my fans working and running correctly with enabled and working EGR, EVAP, and AC. but I've never had an air pump. so that may be a good place to look.

this is very late post but if you have any mechanical ability and a little common sense you can get there with lextech's layout. He is a intelligent individual and has my full support with the work he has accomplished

If you read the whole thread, you would see that I'm using Lextech's schematic or layout...Vortec 4.3 V6 BlackBox to 0411 PCM 4.3 V6. He has my full support also...:D

I re-installed all the A/C pins to the PCM one by one and everything works....Fan turns ON/OFF like it's suppose to!
