When a car is passed on to several owners, chances are the wiring is a mess. How do I KNOW? just a hunch, hehe. Well, at least this is true for us here in the Pilipins.
I got Indra early 2009, sort of like a gift to myself for my hard work in Singapore.
Well, with the “knowledge” (I still feel lacking) I have right now, thanks to my constant browsing of the technica section of grupotoyota (GT), I would say I was pretty dumb back then & was just intoxicated with the thought of having a blacktop (BT) 20v engine…that I bought the car amidst my wife’s vehement objection. Heck, I didn’t even know what version it was! All I knew was that this engine was awesome, oozing with torque in every rpm, well, sort of–starting from 3k rpm until it hits redline which is about 8.3k rpm. What I didn’t consider back then was how the engine got into the car. To cut the story short, not all engine transplants are the same, as I would learn later on, the engine re-wiring should be done meticulously. Since I got Indra with the engine installed, I didn’t know what troubles lay ahead of us.
Again, learning the hard way, I found out that Indra was missing a T-connection to the brake & manifold pressure and that she was running in “limp mode” since she didn’t have an oxygen sensor as well. I also had to change springs since the lowering springs installed were just cut to lower the car. It was purely form…& no function. I simply let Shaggy of Autotech handle all these things for me.
Recently the power door locks & windows one by one started to malfunction. Argh. This time I though of doing it my self, or destroy-it-yourself (DIY) so they say.
Upon opening the door panels, I found out that the oem door harness is still working!! But there was another set of harness for the generic door triggers (gun-type). Basically Indra had 2 door triggers & 2 sets of relays working at the same time!! whoa.
I wanted to purge the door lock wiring system & use the oem harness & relay. So I went and bought the materials, then went to soldering back all the severed lines & putting in a new gun type trigger when necessary. I also had to remove the extra wiring harness used by the generic type triggers & relay. In doing so, I came across the alarm wiring, and . . . oh . . . its beyond words. hahaha.
Since I was already working with the doors, why not fix the alarm spaghetti wiring as well right? It seemed like a sound judgement, though my back didn’t actually agree. It did hurt for quite a few days after all.
Thanks to Monching, for his alarm diagram & invaluable help in troubleshooting my crappy wiring. Thanks to Reggie for the digital multi-meter…it is like a decade and a half until I finally made good use of it! To Donna for supporting me in my little endeavor by buying me a trouble light–yes, its that yellow thingy up there, & last but not the least to Migs & Ethan for constantly “monitoring” my progress & snatching my tools every now and then; come to think of it, every time I chased them for my tools, I did get a good back stretch and a much needed break.
See all those wires, tapes, connectors & what not? I can’t believe Indra can run without them!! talk about lightening. hehehe
