wire harness heeeellp pleeze

[pbouffard]

does anyone one of you chevy brothers have a detailed wiring schematic of an 88 chevy truck c2500 350? what im looking for to be particular is the ecm diagram and what wire in the 2 plugs go to what, i gotta UNF$#CK a prevous owners "repair" on my truck, there are several splices at the back of the ecm, i got some 12v injector wires spliced, i got the knock sensor spliced into the passenger side injector pulse wire, not by me. the biggest wire i need to know is where the knock sensor wire goes to on the back of the ecm harness. the knock sensor wire grounded out on the exhaust and inturn sent the ground to the injector and flooded that side, luckily i just pulled in on my street., sorry for the lack of input lately fellas, kids r in school and well a little less time. thanks
