i have a question, where would i be able to find wire diagrams for my car, and for a toyota

 

being that I'll be running AEM soon this sounds like a cool deal... I think I'm gonna check it out when I get back from Vacation

Score! The complete service manual with diagrams for a 2004 Corolla: http://au.toyotaownersclub.com/forum...showtopic=2012

Edit to Edit:
And here, in post #33, is a torrent for what appears to be the whole Toyota service anthology CD: http://au.toyotaownersclub.com/forum...pic=7385&st=25
(I haven't downloaded it yet since they block bittorrent clients at work)

 

Toyota:

1-ground (brown)
2-trigger (color varies)
3-tach (blue with yellow stripe)
4-V+ (black with white stripe)

These colors are the same on all four connectors. The only one different is the trigger wire depending on which cylinder it is. I have already removed the 2 EGR solinoids, purge solinoid, and fuel regulator solinoid from my car. When I wired the coils I re-pinned the EGR signal wire (from the EGR position sensor) into coil-3 out and used the purge solinoid wire and re-pinned it to coil-4. I had to untape the Miata harness to get the purge lead over by the coils. Inside the Miata harness the stock coils all wire up to only 5 wires. Power, Gnd, 2 signal wires, and tach. The tach leads from the OEM coils are connected together in the harness as well as power and ground.

Some of this information is redundant. I thought I'd explain how I did it. Start off by connecting all four Toyota coils in parallel except for the triggers. Then connect the triggers from 1&4 together and connect it to the Miata trigger for those cylinders brown with yellow stripe. Then connect the triggers from 2&3 and connect them to the second Miata trigger for those cylinders solid brown. If you get those two browns backwards you'll know, just reverse them.

Edit - Ok I'll make it easy on you guys.

Function.........Toyota...................Miata

Ground...........Brown....................Black
Tach..............Blue/yellow.............Black/white
Trigger...........Varies....................Brown/yellow 1&4, Brown 2&3
V+.................Black/white............Blue

Now that I think about it, all the tach wires can be connected no matter what your ecu setup. I may have done it that way I'd have to look.

 

Easy?! Easy would be me giving you $5 to install a set while i'm at work.

 

i just wanted to make sure the wire colors weren't different on my car

 

Well it's easier then cramming two turbos in a Miata engine compartment. :gay:

 

i just bought coil packs off a 2002 camry, just awaiting delivery all for 20 shipped

 

Did you get the connectors with them? I dug in 2 junkyards for 2 hours before I found those plugs. I even tried other connectors from different cars hoping to get lucky. Ironicly the Miata TPS sensor plug sort of fits. $20 is a deal for the set of coils. I believe the dealer gets $130 something for them. Better keep it quiet or the next thing you know there $75 a pop on ebay.

 

my mouths shut now. lol nobody wants to here about COP, there all over that upgraded ignition from moss

 

Around $400 for a system that requires special plugs wires that still have to be replaced periodically, vs $100-200 for a COP setup? I'm listening. I think what you guys are trying to do is very cool.

Cheers!

i just hope i'm able to find the connectors, and i wish i had a welder so i could make it look factory. oh well.

 

$100-200?

I did mine for <$50 Flippy just got his coils for $20. Let the purists spend $400. Not me. I'm a DIY guy.

 

Just grab some aluminum rod, drill it, tap it, and JB weld it to the valve cover. It'll stick.

JB-Weld

 

jb-weld solves everything, i remember my friend cracked his oil pan. and we sealed it with jb weld, and it held for the rest of the time he had his car

 

E X A C T L Y

Not that I've done that.

 

I wonder how cleanly MSI would handle these.

 

And the verdict from a quick search is... no sequential. There is a board in the works for MSII.... but nothing clear yet.

I might get some to keep as a replacement set of "plug wires" though... its like the same cost... and shouldn't burn out like the wires do.

 

so what other advantages does COP offer? besides smoother idle, and increased mpg?
