Help me point a few things out on the harness

I bought two harnesses. One is in the mail right now. Im just testing this harness out and noticed a few things. The ignitor that i have might be from a q45 or my harness is missing the plug.

one side has a square plug with 4 pins and the other side is a 6 prong plug with 5 pins.

the two plugs on the left side obviously go near the battery tray. The maf is on the bottom with another plug near it? the plug in the middle is for my O2 and the other one near the top right is for my coil packs. the rest look like they go near the injectors and CAS.. Any input

I found out that Euro Harnesses after 1991 (or when the front end changed sorry if my year is incorrect) didn't have the ignitor plugs in the harness themselves. In Germany the motor was put in all the way up till 1994. From what I have been reading the CA in Japan was discontinued or at least replaced by the SR at some point and I am guessing the harnesses here must have changed at about the same time. I posted a pic up here earlier showing where the ignitor wiring runs, which it runs along side the drivers side fender into the main body harness. Maybe you have a euro harness for the newer 200's because the ignitor plugs will not be with the harness.

ok i looked at the fsm and its pretty much what you said. The left hand drive models have the ignitor on a separate harness. The right hand drive models have it wired into the engine harness. I might play around with it and see if i can wire it in from the ECU to the coilpacks.

i know you had the question on regarding where the ignitor was wired up. Here is what i found out if you have the CA ignitor with the clips.

This is if you have the Euro harnessOn the 4 pin side of the ignitorred/blue- connected to a black wire on coilpack number 1. THERE ARE TWO BLACKS SO SPLICE THE ONE IN ON THE SAME SIDE THE OTHER WIRES WILL BE SPLICED IN.

red/white- coilpack number 2 also red/whitered/green-coilpack number 4 also red/greenred- coilpack number 3 also red

On the 6 pin side of the ignitorred/green- ECU pin 3 same colorred/blue-ECU pin 11 same colorred/yellow-ECU pin 2 same colorblack-ECU pin 20 same colorred/white-ECU pin 1 same color, not sure why this one is shown in the FSM since it says there is no pin on the plug for this one

Some additional info on the dropping resistors, Wire your resistors intoNumber 1 injector white wireNumber 2 injector yellow wireNumber 3 injector green wireNumber 4 injector blue wireThe red wire is connected on the other side in a series

Thanks for the info, let me know if you get the ignitor wired up. My car is also LHD but my harnesses are also missing those plugs. Luckily my car is stock with CA but I am thinking about swapping my extra motor into something else. Thanks

The plug by the MAF should be for the drop resistor.

i converted the lhd drive euro harness and the car started with no problem, I also made my own resistors, however my cometic is leaking because i did not resurface the block. ****!!!!

Kota you need to drop by the shop.....(if your in the Va beach chesapeake area....) I know ive seen you a fagva i mean dragva.com.....

Check the signature for more details.

PS: Im using the Distributor out of a pulsar..... and regular plugs and wires, Stand alone is on its way....

Glad to hear it started up. There will probably be a few people wondering how you wired up that euro harness as I have been seeing those more lately, and that I don't have the brains to figure it out on my own. I have another euro harness sitting here also and I just recently sent one to Driftek too.

I actually installed a Euro harness today which I got from Germany, and I have noticed the same thing. It wasn't as bad as I though it would be,

You should have 3 plugs on your engine harness where they go behind the battery, the two small plugs (gray and orange), most of these wires need to match them to the regular hook up where they go to the two connectors behind the battery, then you have one big plug on the engine harness beside the above plugs, these wires will go to one end of the ignitor (you need to find the two plugs of the ignitor so you can used them), and the rest of the wires that weren't hooked up behind the battery get put togther to form the other plug of the ignitor. If you look at your foldout pages of the fsm, you will see two ignitors, one marked for LHD, and the other one is for RHD. The LHD is on the right side of the pages and thats the one you need to use, the Three plugs are labelled on the foldout pages as E8, E9 , E10, these plugs are the lower marked plugs right above E116 plug.

I will post some pics of the project that I am doing, I have to say, I am very impressed with the ecu tuning program that I did , the car runs amazing. I retuned the ecu for 440cc injectors and Z32 maf, more boost and other variables, I like it, and I like it alot lol.

Here are the pics i promised

the four pin plug is connected to the coil packs

5ohm 50watt resistors

the five pin plug is connected to the ecu plug

So does this way work when you wire the ignitor from the ecu plug then to the coilpacks, cause thats what i did and i dont know if it works yet?????
