My friend has a 97 S10 Blazer, 4.3, 4x4, 4L60-E trans. She is getting the set of codes that point at the trans harness not getting power. I dont have the list near... its P0753, P1860... etc. I've checked fuse 24 (trans) and it is getting power with the igniiton switch. Next I would like to find out where the pink power feed wire comes into the engine compartment and down to the tranny. I've found a couple pinouts on the c200 bulkhead connector, but all I get is "Ignition Feed", nothing specifying what it feeds. I've probed 5 pink wires in the harness going to drivers side to passenger side along the top of the firewall, and all 5 wires are hot on ignition, with Fuse 24 in or out, so it cant be one of those.

So, can anyone tell me where the specific pink wire is for Fuse 24 in the bulkhead connector? Or tell me the physical location of the harness its in while looking under the hood? I cant quite tell which direction it goes while laying under the truck, I see it for a moment, but then everything gets in the way and I cant really see where it pops up while looking from the engine bay.

Thanks
