If I was to use this mod to add a fan....how do you get the wire to the DB37 connector?
This is one example of what you can do, in this example I used the JS3 output from the MS-I CPU as the input into this circuit (telling it when to switch on/off) and the output routes to Jmp SPR1 which sends the signal out to the DB37 on pin3 which is a pretty good choice since on the v3 it’s not used for anything else. You’d then use pin3 on the DB37 to control your relay which controls your electronic doodad of choice — electronic fan.
Or if I used this boost mod....
Same here:

There's SPR1-4 near the DB37. Which of these are available depends if you're using the canbus or what other mods may have already been done.

Are you actually using CAN?

Just install an extra DB15 into the case and use that as the feed for external IO.
Alternatively install an audio jack for Can usage and then you have spr1-4 for upto 4 I/O lines.
