The pins you mentioned are not for power but SCSI ID#, LED activity light, etc....

Some time ago I bought a Seagate Cheetah ST 39102LC, a fast SCSI hard drive with an 80-pin connection. A little later I bought an adapter for it, to make it work with a 68-pin connection, and also an Adaptec card and 2-drive interior fast-SCSI cable.
None of these items were purchased from the same place, and NONE came with directions. I got the Adaptec card to work with an IBM fast SCSI drive, and it works boffo. But I'd like to add the slimmer Cheetah to my 7600.
And here's where I get problems. Perhaps others here have done this,
and can help me with the connections. (I can't get a significant
rise out of the people who sold me the connectivity parts. I've forgotten
from whom I bought the Cheetah.)
The 68-pin adapter came with a special splitter for the power. Here's my first bit of trouble.
On the adapter there's two rows of pins (2 x 8). The split-power connector has a small interface with those pins, designed to fit into the rows to connect with four of the pins. I just don't know which pins. Here are the pin sets:
. . LED
. . SYN
. . DLY
. . MTR
. . ID3
. . ID2
. . ID1
. . ID0
Now my guess is that it doesn't fit on any of the IDs. Those should be jumped, right? If I put a jumper on "ID1," that'll turn the drive into SCSI ID1, right?
But where do I put the smaller power connector? Over the first row starting with LED, or the second one, on the right?
Any help here?
