OK Mike thanks for the input. One thing tho, no additional power wire
would be required, just a GND return line for each module (maybe that's
what you meant). Everything else you need is already at the injector
connector.

The heat really isn't as deadly an issue as it used to be, as long as
you use devices designed for automotive use (which now often have a temp
range as wide as the old mil range), and PLAN for the temps and power
levels you're going to see. A lot of electonics is already high up on
the engine in many cars; modules in dizzies have been near the heat for
some time, so have DIS modules, which are bolted right to the block in
many cases. Sure you don't put electrics near the heat unless there's a
compelling reason why, but it is manageable if need-be, just more of a
pain. Always tradeoffs.
