I read the manual for my E8 3 times and I am a little dissapointed in the lack of detail in the instructions. I got the full connector pack and they were all numbered but there was nothing that told what they were for, there does not seem to be a CAS connector at all. The instructions tell you to connect this sensor then that one but never tells what color wires are for which pin on the connectors, not very user friendly at all. I searched for a writeup on this but found nothing.Is there something out there that describes where the wires go in each connector?

Download pinout diagrams at haltech.com. And read Mazda manual. All schemes I found.

Search this forum for the proper cas and coil wiring. Thats the hardest part to set up.

tinvestor

like I said no CAS connector and the hardest part is trying to figure out which of the 3 wires for any given sensor is supposed to go in which pin of the connector.

Yhanks funklove I will try to find something on the website. However all I found before was the pinout of the main plugs not individual sensors.

funklove

Tinvestor, have you seen 26 and 34 ?

funklove

I not use all of weatherpack connectors. I use they only for MAP, CAS, injectors, LC-1, air and water temp. Other connectors are from Lada - they are more stronger. The pin's I use in my own.

Download the E6K manual its very informative. Also, there are plenty of posts here and in the Haltech forum with the information you seek.

I found the posts on the CAS and MAP pinouts.

FUNKLOVE the 26 and 34 are the main plugs not to individual sensors. Maybe I am making this harder than it needs to be but it seems to me that when they tell you to connect sensor x, and sensor x has 5 wires they should tell you where to put each wire not simply connect sensor x. I have almost $2000 into this system I expected some detailed instructions from them.

Claudio I will have to download the E6K manual next, hopefully they will pin out the individual sensors on there. Do you know why there is no connector for the CAS in the full connector kit?

I think all the 3-wire sensors (+5VDC, ground, signal) are described in the manual.
This should cover both the TPS and MAP sensors.

The water temp and air temp are 2-wire, and there is no polarity on them - so it doesn't matter which wires go where.
The TRICK with the water temp and air temp sensors when you install the pins is that the silicone seal goes on first, THEN the plug body, and THEN you crimp the pins on.
So, the pins get crimped from the front of the plug body.

All the other WeatherPak connectors are "crimped from behind" - the pins are installed on the wire (after you slide the silicone plug on the wire first!), and the pin in then inserted from the back of the plug body.

As for which plug goes for what...if you've ever seen a fully terminated harness, you'll understand what goes where.
Technically, it doesn't matter what plug goes where - electricity is electricity.
The exceptions are the water and air temp sensors...and the MAP sensor.
The TPS already has a plug installed, so you need to find the corresponding plug and pins to make them fit.

The large 7-pin wide / flat plug is typically used for ignition outputs.

The white 5-pin (2 top, 3 bottom) plugs are used for the fuel injector harness - i.e. 4-cylinder sequential / 2-rotor staged.

There is no dedicated "CAS" plug as you have mentioned.

Now, for the rant...
These systems were (and still are) NOT designed for the DYI'ers.
They were designed and made for authorized install and tune shops that are competent to handle such components.
This is one of the problems when companies like this want to make more money and start expanding when they see the money start to roll in.
"Growing pains."
You cannot fault Haltech for trying to make money; making money is the mantra for most businesses.
The company is relatively small, and customer service is not always priority one.
If you wanted top-notch support, get a MoTeC, period.
If you can't afford a MoTeC, corners are going to get cut - live with it.

If you're getting frustrated with problems like this, I'd highly recommend finding a shop that can take care of it for you.

Thanks Ted I dont fault them for wanting to make the dough just thought that a few more drawings and notes would be an appropriate way to help out the people they are growing with. All the three wires are described in the E6K manual that I looked at last night online.
As for a shop the only local one is A-Spec and I HATE shawn and will never allow him to touch this car.

since there is no CAS connector what is the cleanest nicest way to wire it in?

Should I hard wire it inside the CAS or hardwire it outside the CAS or (I really hate this idea) should I just hack the CAS connector out of my perfectly good stock harness or is there another/better way?

Funklove: sorry, I didnt even notice those were links, they are very helpful.

Who needs tech support at Haltech we have such a wonderful community here

Thank you all for the amazing amount of help and patience.

Understandable.


Are we talking about your 10AE?
If so, with any of the Zenki FC turbos, I just *splice* the wires at the ECU plug.
Most of us install the Haltech ECU's in the original area like the stock ECU.
Once you remove the stock OEM main engine harness, the "ignition harness" is still there, since the ignition outputs (to coils) and CAS / ignition input runs through the power harness - how convenient.
If you want to somehow put the car back to stock in the future, you just cut off the Haltech splices and tape up the leads back - viola, back to stock!
Since you're running an E8, I've had zero issues with noise using this technique - and it saves you running wires all the way into the engine bay!

Side note, I've heard of all kinds of headaches with ignition input noise through the CAS plug.
You almost have to hack the stock wiring and wire the Haltech input leads right into the CAS itself just to get the good noise rejection - royal PITA!


Sorry for being a little rough in the reply - it's been a bitch of a week so far!

tinvestor

well as for running wires into the bay I have NONE so I will need to run them all the way in anyway so you are saying I should just run the wires all the way into the CAS and just remove the stock wires and connector that are coming out of the CAS. Right?

I have removed the entire ignition harness, and emission harness.

If you wish to put plugs(not using the stock CAS connector) you can use any of the "weatherpack" connectors. If you contact the person that you bought the ECU from, you can ask for the M/F(J16 & J16F) connector that is typically used with the HallEffect Sensors... We have both Male and Female, and you can terminate it yourself...

Just make sure that when wiring, that the RED wire is now 12v. Not a ground as it was on the E6 series... So your connections should be this way:

CAS-->Haltech

Red-->Haltech Trigger input(Yellow)
Green-->Haltech Home input(Green)
White-->Haltech Ground(Blue)
White/Blk-->Haltech Ground(Blue)

ALSO!!! Make sure that the colors that you are referencing, are the wires coming out of the CAS BEFORE the white OEM connector. As the colors do not match(Interestingly enough!)

Good luck.
