I've added manual info alongside your observations:
Pin 1 = Blk/Red .. Gn/W +12 to TCC
Pin 2 = Grn/Red .. Br/R TFT
Pin 3 = Blk/Brn ... W/R TFT
Pin 4 = Blk/Grn ... Bk/Y SS1 to PCM
Pin 5 = Grn/Org .. Gn/Y +12 for SS1, SS2 & timing/coast
Pin 6 = Blk/Wht .. Bk/Bl SS2 to PCM
Pin 7 = Grn/Yel ... Bk/W TCC to PCM
Pin 8 = Grn/Wht .. Bk/R EPC to PCM
Pin 9 = Red ........ Gn/O +12 to EPC
Pin10 = Wht/Red .. Bk/O timing/coast to PCM
Connector shows as round with a flat side up. Pins numbered:
1 2 3
4 5 6 7
8 9 10
I think I'd start by trying to get a +12 volt reading, try with key on, but engine off. Don't think one ohm a big diff.
