92-94 c200 plug pinouts

[mOBSley]

After trying several google searches and forum searches with no luck, I figured I’d ask here. Got a 94 4.3 truck, swapped to a 92 350. We installed the engine harness into the truck and found the engine harness plug near the ecm to dash harness plug was entirely different. Several colors are the same, but there’s 5 or 6 different colored wires. From my research, I think the connector is labeled either a c100 or c200. Any one have a schematic on both a 92 and a 94 on this plug?

That is the c200 and give me a bit I may have them

GM factory service manuals for '92 and '94 can be found here.

Not sure if that connector pinout is in there, but it might be worth a look.

Well, just now got to the truck, and found out I only have half of the info I need. I’ve got the c200 pinout for the 93, but cannot find any info on the 94 c200. I’ve even paid for alldata and it’s only showing the location of c200 on the 94 model. Anyone able to help on this?
