I need to do some electrical troubleshooting and need to know the location of the Body Control Module on 2000 SL1 models. Can anyone help? Anyone know of a good source for wiring diagrams? By the way, both Haynes and Chilton are very deficient on this technical aspect.
Thanks, John |
I have the wiring diagrams for just about all GM vehicles. What exactly are you looking for the pinouts for?
#1 is the location of the BCM for all third generation Saturn S-Series http://www.differentracing.com/mike/parts/bcm.gifEdited by: Low Saturn |
Mike,
Thanks for the BCM location information ... I'm tracking down an open circuit in the keyless remote system for the trunk lid servo. It works sporadically ... not a key fob transmitter problem either. Can you email (pdf) the 2000 wiring diagrams for this circuitry? Thanks, John |
Hello mike,i have some problems with my car alarm, and with the BCM can you send me de BCM wiring diagram for the 2002 Sunfire Vin F 2.2Lts Ecotec Engine. ? i think its the same for the Cavalier [img]smileys/smiley19.gif[/img] TNKS... |
I''ll take a look when I get home from work.

I have a 2001 sl2 autotrans The underhood fuse box started smoking and when I inspected it I found out that a previous owner had butured the front harness. I grabbed one from a pick n pull. Thought I could pull the connectors out of the uhcm and crimp the new harness in. Went to work and when I came back one of my kids had tried to help and now I don't know the location of each wire in the far left connector. I'm in over my head and I think the only way im going to be able to fix this is if I can come up with a pinout diagram for the front harness . Please tell me you have one or know where I can view one online. Thanks in advance for taking the time to help out. |
Try using Google to search on the phrase
2000 saturn sl1 pcm wiring diagram and rummage through the images that google pulls up in the image section of the results. Either that or get a Field Service Manual (a REAL Saturn one) off Ebay. |
