no need for pictures of the plug. I have the same one on mine. I'm with Chris there is probably a sensor in the tcase that the computer wants to hear from telling it its in 4lo so it will shift properly. You might be able to find a schematic of the transfer case and see if there is some wires that could be jumped to tell the computer its in 4lo. I'm not a big fan of the push button crap either, and my plan was to replace it with a 231 when it failed. Looks like that might pose a problem.
BTW I thought those horns were golf clubs... i thought it was funny that someone would take a bag of golf clubs wheeln....

this may help, but im looking for the "how to" thread where the guy shows how to fix the problem

[pjg1173]

here is a tread on another board that talks about it and gives vauge wire locations. look at post #57
http://txzr2.com/board/showthread.php?t=1172&page=2

[t01blaze]

YES! thats the info i was looking for...i think this may be the problem afterall

[pjg1173]

here is another one with some pic's. I'm not too sure of what year S10 they are working on but the concept should apply. http://www.zr2usa.com/mboard/index.p...ic=18091&st=40

If you find that thread or tell me what wire it is I'll PayPal you $1.00

this is the thread here, its the black/gray wire from the tccm. you should also watch the video linked in the thread. just cut the wire and try grounding it.

read post #19 for system description, post #25 for wire location, and post # 30 for the fix and a video.
(this link puts you on page 3 so you need to page back and read previous posts...but you knew that anyway)

[t01blaze]

you owe pjg1173 for the find if it works!

[Baggey22]

I'm slightly confused about WHERE this wire actually is? The grey/black one. I understand all I need to do is splice into it and ground it whenever I need to use 4LO, I just need to find it.

[t01blaze]

its behind your passenger side kick pannel, thats the TCCM

[Baggey22]

So if I pull that kick panel all I have to do is find a harness with a gray wire with a black stripe then somehow ground it when I need it?
Cause in ONE of those threads there was a picture from what looked like INSIDE the engine bay
This one:

[t01blaze]

the wire goes from the tccm to the PCM. thats a pic of the pcm. if your putting your switch inside the cab for 4 low, why would you want to run a wire through the firewall when you can get it in the cab

[t01blaze]

heres a picture i just took. i hope they help. make sure you get the correct wire, cause i saw 2 grey and black wires. A schematic will help, but I do not have one. you can use a DVOM to check continuity between the PCM and TCCM to find the correct wire if you are not sure.
(in the video on zr2usa, the guy got it in the cab at the TCCM, so i thought this would be easier, but you can do it however you like)

[pjg1173]

I would definatly pull it from the connection in the kick pannel. less of a headache pulling wires

[pjg1173]

Baggy, I found this at the bottom of the article there is a link to a scanned paper with the pin #, wire color, and what it does. Its a little hard to read but it says "pin 1 grey/black - PCM 4wd low signal" http://www.kylestubbins.com/node/11

found this on google trying to find a schematic/pinout thought it might help.

I'm pretty sure this is the wire you want(in red)

EDIT : Beat me to it, pjg1173! ^^

[DieselS10]

Good info guys!

[Baggey22]

You guys are the best! So let me get this straight.
I take that harness out of the kick panel
Take the gray/black wire in Pin #1 and splice another wire into it
Run that wire wherever I want it
Ground out that wire whenever I need 4LO and keep it UNgrounded when I don't

Sound right?

yep... t-into it. run it to a toggle switch on your center console and wire the switch right to a good ground.

[Baggey22]

I was thinking about doing the switch thing but I didn't know if it would actually work or not. I think I'm just gonna get a gator clip that has a rubber sleeve over it. so when I'm not using 4LO it won't accidentally ground itself out.

[ChrisInVT]

You're all for rigging shit aren't you?

[Baggey22]

I'll do the switch thing if I know it'll work, but if not I have no problem just rigging up a gator clip.

You're just jealous cause I can wheel and you can't

[ChrisInVT]

I go wheelin almost every day.

Remember, I have many toys

[Baggey22]

I'm having a wicked brain fart on how to wire a switch to make my 4LO work.
Can anyone explain how I'd do it on one of my rocker switches?
One of these:

[ChrisInVT]

Middle one is power, one pole is switched the other is a ground (for the light)

There's a schematic on the side of the switch.

And I'm never listening to you about checking out a truck again

[Baggey22]

Well I'm using the switch to ground out that wire from the PCM. So would that wire I'm trying to ground out go to the power pole? I don't care about the switch lighting up, I have like 4 of them in a row and none of them do.

[t01blaze]

use a dvom and check continuity through the switch. what ever 2 poles complete the circuit

[t01blaze]

or use a test light and some jumper wires to make a circuit off you battery posts to check the switch. whatever 2 light the test light will work for ground

[pjg1173]

Have you tried this yet? I'm courious to see if it works. I took my truck out this weekend and noticed in 4lo it won't shift out of second gear. I'm trying to figure out if this is normal for a 4l60e. let me know if you have the same issue.

[Baggey22]

I haven't tried it yet and won't be able to for a few days. My truck is at the mechanics getting the e-brake cable replaced and hooked into the 8.8. But I am going wheeling on Saturday with a few people so I'll MOST LIKELY have the mod done so I can get out of first gear on trail.
I'll let you know

[pjg1173]

take some pics on how they adapted the e-brake cables. my truck is due this month for the state inspection and I have to adapt my cables to work on a D44. I have an idea on how I'm doing to do it just been too lazy to try it...

[ChrisInVT]

Holy shit, do you do any work on that thing yourself?

[t01blaze]

so did the tccm wire fix the problem or not?

[Baggey22]

Idk yet. The truck is still with the mechanic. He's been backed up, and it's finals week for me so I haven't really been thinking about the truck. I'll try it as soon as I get the truck back (I'm thinking Thursday or Friday)

[Baggey22]

Update: I got my s10 back from the mechanic. The ebrake is done. So today I went to tackle the problem of not shifting in 4LO. So I took the kick panel down and everything I have is NOTHING like those pictures.
I grounded out what I THOUGHT was the correct pin and as soon as it grounded the truck hit an extremely shitty idle and almost died.
I have some pictures of what I have, maybe someone can help.

[ChrisInVT]

Well, that looks like your ECM...

[Baggey22]

Update: Today was just a bad day for my s10. Like I said earlier I couldn't find the PCM (as pointed out by ChrisinVT)
But then to make matters worse I went out on trail (same ones I did a few weeks ago) and totally fvcked my transfer case up. I'll get pictures tomorrow but SOMEHOW (I think I have an idea of how I did it) there was a bolt head holding a small spring in and it got sheared off causing ALL the transfer case fluid to drain out. So I had to wheel to the road and then drive home with an empty transfer case.
Thing is it didn't act MUCH different or make ANY noise while driving back after all the fluid was gone.
So what does everyone think? fix the hole and refill it OR get a new case?
Other suggestions?

And I'll get pictures uploaded later of today, I have a few

Which one looks like the ECM? That's two different parts. One was in the kick panel, one was bolted under a dash piece I had to remove to get the kick panel off.

[96superflow]

it looks like the one with two plugs is your ECM. or atleast when i stripped down my 92 blazer with the vortec v6 thats the part i pulled and figured it was. Yours is the year they were switching all the shit around with motors and all right?

[Baggey22]

My truck is all kinds of Frankenstein. The frame and body is a 1995 s10, but the motor (or so I'm told) is from a 1993 Blazer, the transfer case is from ChrisInVT's parts truck (1991 s10 maybe? I forget), and the transmission I have NO idea what truck that belongs to.

[BillaksBlazer]

you probably burned up the bearings inside the t case. get a new one.

[Baggey22]

How hard would it be to get a rebuild kit and go that route?
Is it even worth it?

[wrekd]

I would just get a new case

[Baggey22]

The issue is GETTING a new case. They're not extremely common around here and IF I can find one in a junk yard they want hundreds for a used case. It's stupid.

[Chevtech]

The one with the yellow connector should be your airbag module, probably don't want to mess with the wiring for that one.

That sucks. I could get em all day here for around $40-$50.

[Baggey22]

I'm gonna call around tomorrow and see what kind of prices I get.
Wrekd, if it's like stupid expensive would it be too much trouble for me to PayPal you the cost of buying one down there and sending it up to me?

[BillaksBlazer]

The rebuild kits only contain new seals. You would have to buy the bearings seperatly from a tranny shop or something. They would probably get you used stuff. so like wrecked said a new cas is the easiest route.

The thing is I'll have to go pull it. Those prices are from Harrys-u-pull it. I'll have to see what the other j-yards want for one. Im guessing around $75. I'll call around tomorrow and see what prices I can come up with.

[Baggey22]

Thanks Wrekd, I'm also gonna call around tomorrow and see what prices I can get. I also MIGHT have a CraigsList lead on one in NH. But we'll see.
