new to forum and i cant find what im looking for by searching. soo im hoping someone can help me. i am needig the wiring diagram for a 1996 gmc suburban with a 454 and 4L80E and 4x4. despite my better judgement i let a guy put a tranny in my burb and he has wiring screwed up. im not taking it back again and im going to trace it out myself. anyone that can steer me in the right direction or has it themselves. thank you for your help

specifically i have a short in the maf,egr, evap circut. and that is with all items removed from circut and i have the loom wide open

 

have you checked out any of the electronic manuals on EBAY -> GMC SUBURBAN 1996 1997 1998 1999 REPAIR SERVICE MANUAL | eBay

 

No but I will check that shortly. Thanks in2pro

 

Another option to try is ALLDATAdiy.com :: Leading Source of Diagnostic and Repair Information this is a yearly pay site but has very good info, I have the service manuals for my 07 Tahoe but I use the alldata site for my wife's Dodge minivan as the manuals seem a bit harder to find...
