Well, it started out with a salesman putting my Blazer into 4wd and not been able to get it back into 2wd. The 2wd light on the panel would blink 3 times and the TCCM would click but nothing would happen.
So got under the truck and checked the actuator, it worked, checked the actuator motor, put it under load, it worked.
Traced the wires up to the TCCM and found the wiring harness and plug was severely corroded.
So I need a TCCM plug and about 6" of its wiring to fix my own. I would put this in the wanted section but i am unable to since this is only my 3rd post.
My TCCM is # 15741322 and it has the large blue plug.

Anyone help me out?

 

Maybe someone would be willing to look around a junkyard next time they are out and see if they can get me a plug. Out of the six vehicles at my local junkyard, all the plugs are cut out of them, must be a normal problem with these vehicles.

 

altho i don't personally condone sales and such outside of the classifieds, get me a pic of what you exactly need and when i go to the junk yard either just before xmas or after i'll see about pricing and getting you it. also need to know where this is going so i can get you a price. only request i have of you is that you get your post count up to 15 by the weeks end and make legit and credible posts that follow the rules

 

You should also be able to pick up a new pigtail from the dealer. It isn't going to be as cheap as a junkyard part, but it will be new. When you do get the replacement, do the wiring one by one for the like colored ones to make sure that you don't get anything crossed up.

 

I'll just keep responding to this post until I get my post count up. I can take pictures but then I have to find out how to post pics in here. I will see what I can do.

Swartlkk, a new wiring harness is $118 cost price, free at our junkyard if they had any.

 

You should be able to find the appropriate terminals from PCSConnectors.com. It is a 32 pin micro-100 connector. Then just replace the terminals on the wires that need to be replaced. The terminals are cheap!

 

if you have something like a photobucket account you just need the address for the pic and put [img] [/img] tags around the link - eg [img]http your link here[/img] and ur pic will show here.

lol i checked out that link u posted swartlkk and found a 32 pin micro-100 connector - looks like this and for $2 in either blue or red go this way man. itll be much cheaper than me getting it and mailing you it.



just to make ur life easier - here's the direct link to that item - for about less than $10 u can get 32 female terminals, the connector, and the top half lock mailed to your house and its all brand new. - http://www.pcsconnectors.com/12110207.aspx

 

I'm not sure if that connector will properly fit the TCCM. I was more leaning towards the purchasing of new terminals and reusing the original connector.

 

ah i gotcha. link for just the terminals - http://www.pcsconnectors.com/12146448.aspx

 

Damn, their shipping is retarded. I ordered ten 16/18 female connectors, maybe 1/2 ounce weight or so, and they want $24 shipping.
