Before I would start to install BS3 I want to clear out both the interior and the engine bay of the unnecessary harnesses and hardwares. The stock main harness and the ECM came out together with the Ostrich and data logging setup. Also I've removed the TechEdge WB O2 setup, since the BS3 has its own. It was a good feeling to get rid of the old harness, it was far from its best shape. On the other hand this harness included some functions, which the BS3 unit doesn't cover. These are the hot wire to the starter solenoid, four wires for driving the wiper motor and two wires for regulating the generator. I have to take care of these functions separately.
I've decided some times ago, that I'll have a BS3 at sometime. Finally the decision came earlier, as I thought it would, mainly, because I was getting tired of solving problems around the stock harness and ECM. Hopefully this will work as a champ. Will see...
It was quick decision and it happened even quicker. I've sold my AE86 Toyota Corolla. I've quite a few reasons, probably the most important, that I'd no time in last two years to finish this project. Lately, I'd bad feelings whenever I looked the car. So now it's gone with all of it goodies, take a look at the last picture I could take.
