Madness?? This is not madness..this_is_SPARTAAAAAA
Wiring the TEC3r. (Or, how to make something really simple…really complicated for no apparent reason )
15min per day.....eventually it WILL get finished.
Ive been lazy, especially in light of working on the wiring for the TEC3r. What seemed like a simple idea has mushroomed to a colossus that threatens to kill me if Im not careful
See, I had this idea.....I saw all these unused connectors from the stock harness and thought "hmm, why dont I just use those instead of overlaying everything....make use of whats there". Yeah, that seems simple enough. Weeks and weeks later after tracing wires and wiring diagrams, trying to sort out what connectors would be appropriate for what tasks...do I even have enough plugs?....why the hell am I doing this again? Then theres translating from Electromotive-speak to Mazda-speak (wait, when they say the tec3 needs this, is this that in the wiring diagram?
Amazingly though, I am making good headway and I am almost done with the wiring between the two manufacturers. Its been a learning experience for sure. Heck, I am even delusional enough to think it may all actually
work. (definitely NOT tuning this thing after all this headache
Ever do something really stupid? No, I mean REALLLLY stupid? Well heres my version of “no srsly..WTF was he thinking? ”
As per the above plan, I was thinking to make the connection of the TEC3 plug and play. If there was an issue with the unit, I could always fall back to the stock ECU. Makes sense right?…Um, not so much.
If one thinks about this and the components of my build for say…2sec, this is a ridiculous notion. I have a custom intake manifold that uses non stock sensors, the VAF and associated hardware will be removed, boost control is gone, a ton of stock connectors are being retasked for other purposes, etc, etc
Why on Gods green earth I thought rewiring things through the stock harness was a good Idea… Ill never be able to explain (temporary insanity? Swamp gas sickness? smokeable “Herbal” products?…ugh ). At that point I should have stopped and simply done the smart thing and overlayed the stock harness with a new harness…..but that’s NOT what I did. I kept going…..cuz Im dumb
Heres the tale of my decent into madness.
Not having done anything like this before I looked at what others had done in the past here and on other sites. Surprisingly (despite a lot of usage in high performance vehicles for decades), there is little information about the installation of the TEC3 unit.
If I were to integrate the wiring of the TEC3 into the mazda wiring harness I needed to know what went where(and how). This is the first issue…language. You see, what Mazda calls a thingamabob, electromotive calls that a doohickey. Not being fluent in either Mazda-speak or electromotive-ese I had to translate both to English. Oy vey!
I needed help.
