After replacing my shift solenoids and the ignition switch i am, sadly, back to checking for an intermittent open or short in the transmission control circuits.

Can anyone here provide an end view diagram of the IP Harness to Body Harness Connector C203 for a 2002 Blazer.

I have a 1998 manual but have already discovered that Connector C101 on 1998 Blazers is different than C101 on a 2002. (Thanks again Les for your help on that one!)

I'd like to be sure that C203 wasn't also changed between 1998 and 2002. C203 is a very large (116 pins) connector and the drawing has three pages of pin descriptions but I only need the pages or just the correct pin locations for circuits 1390 and 1020. Any help is appreciated!

Les? Captain? Swartlkk? Anyone?

The best help I can offer is to get a factory service manual for 2002. It will save you time and you'll know the info is 100% accurate.

 

Yeah well Rusty... That makes perfect sense. However this is my third Blazer having previously owned a 1988 and then a 1998 LT. To be honest I'd trade this '02 LS in a heartbeat to get either one of them back.

I just can't bring myself to cough up the dough for the '02 manuals as if I don't solve this intermittent limp mode problem soon, I might just push it out to the curb with a "FOR SALE CHEAP " sign on it! BT

 

Never-mind and thanks anyway! There's more than one way to get a cat skinned!

Now I'm just building up my post count. I only have 98' and 99' service manuals. Sorry I couldn't be more helpful...

 

For 2001 Blazer: (from 7 pages of decriptions for C203)

116 pins
circuit 1020 = pin K4, pink wire
circuit 1390 = pin B7, white wire
both are "OFF/RUN/CRANK VOLTAGE"

 

Thank you Les!

I appreciate your reply! BT
