Hey y'all! Hope you're doing well, here's my situation:

I bought this 1993 chevy van 30 from my old boss, it's a cutaway box truck, from what I can tell it was manufactured in Canada and as such its VIN doesn't properly decode properly on the online vin decoders.

I THINK it's a g30, but it could be a p30 and I'm not sure how to tell the difference.

When I got it, it kept blowing the gauges fuse, so I opened up the harness and found that one of the pink/black wire was melted into the fuse box, into the bulkhead connector and along the harness. Went to run a replacement and found that other wires had also shorted and melted thru their insulation.

Come to find out, a while back they had the transmission rebuilt and pinched the Water In Fuel sensor wire in the case and it partially shorted without quite popping the fuse (or my old boss upped the fuse to keep it working, not sure.)

After discovering this, in my infinute hubris and unearned confidence I decided that I would just RIP out all the wiring and redo it myself.

Cut to 11 months later and I've mostly got everything figured out, but I'm missing a couple of things.

Could someone with factory wiring diagrams shoot me over the pcm chart? My Chilton and hours of googling haven't turned up results on a few of these wires.

Or a pinout of the c100 bulkhead connector?

My Vehichle Seed Sensor Buffer has a dark blue wire I can't figure out where it goes.

Ugh. Sorry for the long post, I've been pulling out my hair for the last 2 weeks trying to get it ready for hurricane season diaster response and I'm stuck.

Thanks y'all!
