Pics might work better for those of us that dont have access to parts books.

Pictures and where you found them would be most helpful.

ill see what i can do for pics...the denso seems to be part of the distributer harness which goes inside the car, opposite the driver..could this be an igniter or anti detonation module? the other has around 5 pins...anyway..im just sorting out a harness for engine only running, and dont need all the other accesories that are there.....i have deleted all the diagnostics probes for testing and will back probe them on the engine if need be..looks like they are only there to make testing all items easy accesable from 2-3 diag plugs..i have left the pins in the plug for code reading and will i.d these and fit them into the sandproof box when im fitting up the conversion.its going in another sandrail....ill get back with somepics....if i cant i.d them before hand..thanks guys

If its an 85-86 turbo, it could be the knock control box
