Hi again ! A problem with scsi harness (powercolour classic)

I used a block of soft wood to connect my scsi cable to the harness.

I positioned the cable over the metal points, then used the end of the wood block to push the cable into the points.

You could also put the whole thing, including the wood, into a vise and press it together.

I used the end-grain of the wood (the end on which you can see the tree rings) to push in the cable, as it's soft and allows the pins to enter the wood slightly without bending them but still applies good pressure to the cable.
