You don't really get a choice with some things, like a fuel pump relay!

I had to order a soldering iron before I break it out. http://www.amazon.com/Soldering-Station-Features-Continuously-Variable/dp/B0029N70WM/ref=sr_1_1?ie=UTF8&qid=1375125137&sr=8-1&keywords=soldering+iron
I decided my soldering gun might be a bit too much for this job.
Well, it's done...now to see if it works! 
How long did it take you to build?
In reply to fujioko:
It took me about a week and a half to build it and the stimulator working a few hours in the evenings.
By golly it seems to work! 
It took me a few minutes of trouble shooting to get the wheel settings on the stimulator correct, and to realize I forgot a resistor that was making one of my ignition outputs not work.
I am using a msq file for the Dodge 2.4 turbo engine that I found on line. It uses two spark outputs in a wasted spark setup ad bank fire for the injectors (two groups of 2 injectors). The two spark outputs alternate like I would expect, but for some reason both injector outputs "squirt" at the same time, and at half the rate of the spark outputs...seems odd to me.
Now the fun part of getting the program set-up begins.
The injector outputs will fire together if set to skmultaneous, and alternate when set accordingly. Its under basic settings, engine constants.
I'm still learning my way around tuner studio, and found those settings after I posted. All of the sample tunes I have for this engine have the injectors set to simultaneous rather than alternating for some reason. I still have quite a bit to learn.
On a four, you're not going to notice much difference, except at idle.
I decided to add a few circuits to use up the remaining output pins before I seal up the board. I added a knock sensor input, tach output, shift light and launch control. 
Here is the final board:
