If the devkit is a DTL-H, the instructions are pretty much the same as retail systems. For DTL-T (e.g. DTL-T10000 or DTL-T15000), there is lots of info here, including a link to a disassembly guide: https://archive.org/details/ps2_tool_guide/

Thats awesome. And yeah I have both a TOOL and a TEST, the TOOL is the problem child the TEST works a treat. Both of them have been officially destroyed and I tend to get a bit antsy about letting them show in public.
