hey guys, the main plug for my tccm has corroded, and i need to replace it in my 2000 blazer.
i cut a tccm plug thats in good shape, out of a 2000 blazer at a scrap yard.
alot of the wires are the same color, so im unsure of how to match them all up.

does anyone have a wirring diagram or know where i can find one?
or has anyone ever done this before?

any help would be awesome.
i wanted to go wheeling this weekend!

thanks!

 

just clean the stock plug and add electric grease

 

Usually works but not always.. Clean with intake cleaner. The dielectric grease is really important.

Otherwise .. dont the wires exit the back individually? Tape old and new connectors together side/side and cut/splice one at a time.

 

yeah, ive tried cleaning it. i already replaced the tccm.
and i tried all of the above, plus letting it soak in coke for a day.
but i still have no signal. the t-case motor, 4x4 switch, and main wire down to tcase is brand new. gm mechanic that did the main wire, said it was the plug. but i havent been able to clean it and get it to work.

 

Fully understandabe, then.

do the wires exit the back individually?

Tape old and new connectors together side/side and cut/splice one at a time.

Believe me, if you can do it that way it beats the crap out of matching up color codes.
