Well today I decided to wire in the flasher. This took quite a bit of time and was a really tedious task. As with most small point mods, I used Kynar Wire, leaded solder and no clean flux.
I began by soldering all the points on the motherboard first, This took a huge amount of patience.
Then I found a location for the Teensy and soldered that onto the other end while shortning the wires, then tidied up the wires with a bit of electrical tape.
Next I need to finish the software side of things and get it all going.
