Lewis7789 2002 Protege5 build thread (tons of pics)

[Lewis7789]

Well fuckity-*******-****.

Yeah, my ECU's (both the JDM and USDM KL's) have the 95 Milly ECU setup like the pic on the right. So they are OBD1, eh? Well that's good and bad I guess.

I'm still at work until 4:30 so I can't really get into the diagrams and stuff to much until later. Balls...

 

[Joost27]

they might be OBDII, im not positive, but they are extremely similar to the OBDI ecus, and last I knew OBDII mazda ecus atleast for the KL went 3 letters and 1 number like KLG8 and OBDI went 2 letters and 2 numbers like KL47

 

[Joost27]

updated picture. Shows the OBDI 93 mx6 ecu (KL01), the 95 millenia just has one extra smaller connector.

 

[Lewis7789]

Yeah, it's the middle one for sure. And the KLK1 ECU is like the middle one too. I had a KL36 ECU and it was only 3 plugs like the one in your pic.

And the 4 plugs at the end of the Milly harness are yellow with two lines of pins.

 

[Lewis7789]

Yay for Chris (03zoomzoom) for emailing me the pinouts for the 1995 KL47 ECU.

Now I've just got to try to make sense of this nonsense...

 

[Joost27]

thats awesome, glad its finally making progress after the small set back. Nice that what he provided has the voltages that things should read which will be good for troubleshooting if it comes to something not working.

 

[03zoomzoom]

Just glad I could help buddy! The pinouts for the p5 are headed your way this morning.

 

[Lewis7789]

And thank you once again, Chris.

 

[HKPRO5]

So with this do you still need help? If so whats left to do?

 

[Lewis7789]

Now for the kicker, the harness does have four O2 sensors and so did the car. So it should be OBD2 and Jon verified it is a 1996 Millenia. Back to more research tonight after work...

 

[Joost27]

i read yesterday that 95-96 millenia had 4 sensors, 97-98 had 2, 99-00 had 4 again. Also, have read that no millenia was OBDI. As for the whole 96 issues, does you wiring diagram give a date or VIN range for 96 cars? if so I wonder if his falls outside of that, because it certainly is a 95 ecu and harness.

 

[Lewis7789]

I'll look up the VIN numbers in the wiring diagram when I get on my home computer. But will they match the KL block numbers, because I don't have the VIN for the chassis though I think maybe Jon can get it from me if he still has the chassis.

Pablo said the wiring we did in the engine bay is still fine and all I need to do is;
I just jump (P5) pin 51 to (KL) 4A then 71 (P5) to (KL) 4B.

Can someone verify?

 

[Joost27]

anything in the engine bay should be fine, the issue you would have ran into would have been once you started connecting the kl harness to the p5 harness at the ecus for power, ground, clutch switch, etc..

Edit on top of what you listed you need:

KL Pin 1c to P5 Ignition switch start wire
KL Pin 4I to constant 12v source
And I would ground 4A to chassis rather than tapping the P5 ecu ground. Plenty of room to ground in the car.
The list above doesnt show which pin on the Kl is for clutch switch, that needs to be hooked up to P5 Pin 6

are you going to be using the dakota digital tach adapter or something else?

my first thought was 4I for power but I changed it to 4B because 4I is the Vref for sensors, only testable when the relay is "ON". 4B is listed as power supply, testable under switch (RELAY) on or off.

4A can go to either one (GND or jumped to the P5 ECU)

 

[Joost27]

its 3I that is the vref, 4I according to the list above is power too just like 4B. And I agree 4A can be grounded either way, but tapping less wires is always a plus in my book when u can jsut run a length of wire add a connector and find a bolt.

 

[jonridinhi]

I can verify that it was a 96 milly. I had the title but the scrap yard needed it to take the shell. It is OBD2 and had the port and 4 o2's as discussed above. That is interesting with the ecu. The wiring did not apear to me to be muched with and the previous owner did not even change his own light bulbs so I doubt he did any swaps. The only thing I can figure is a change in year range. I was working on the wirring on paper but did not get quite that far before I moved on to a bigger project. I will see if i got any any of it saved....

 

[Joost27]

yeah im sure it was a 96, but might ahve been early on before switching from the KL47 to the KLG8 ecu and with the switch requires different harnesses. Both 95 and 96 had 4 o2 sensors, and I have seen that no millenia was OBDI which makes sense that yours was OBDII, was likely a very early version of OBDII tho since the 95 was not required by law to have OBDII yet. Thats why VIN would have likely been able to help determine if it was meant to fall in the range covered by the 96 manual, which after seeing his harness plugs I would say that it does not fall in that range.

my bad, you're right

 

[Lewis7789]

Sweet. Thanks guys.

Pablo, is the wiring we did for the disty still good as well? I don't remember what we tapped/jumped. I should've written this stuff down...

And I don't think there is a clutch switch since all the Millenia's had automatics. We grounded two wires in the tranny plug to the chassis to trick it into thinking it's in Park.

And I picked up a Dakota tach adaptor like you did, Justin.

 

[princess peach]

yeah you should be alright, both of those wires go to the relay so they match the injectors
