wiring problems in my Z6 EF hatch, need some info
 

ok i need one last bit of help here hopefully

i got my old wireing harness pulled, and it was fucked! i have a new SI harness i bought off here about a week ago and im getting ready to put in.. but i dont recognize some of the plugs.. i dont see em on the old harness.. are they just not needed and got snipped or did i somehow get the wrong harness O_o

btw if anyone has the wiring info for the dizzy plus for OBD-0/OBD-1 please let me know, i've been lookin for a while but seem to get diffrent answers each time

also, on the SI harness, will i need to switch over the injector plugs? they look the same as the ones from the old harness and are colored the same as well.. i want to do as little wiring as possible to avoid any fuckups

im currently useing a boomslang conversion harness to go from OBD-0 to OBD-1 so i can run my PO6 and my Z6 dizzy.. i've heard you can stay OBD-0 and use the A6 dizzy and a PM6 (i think) ecu but that seems kinda ghetto :l

anyway any help is always appriated, untill then i'll be ------ with it alone

also i dont have a way to test if things are right at the moment, i dont have a main relay.. i tried repairing my old one but every time i try to repair one i break a ------- contact or something and i get a constant ticking, so i got one on order from e-gay

Dx or Si originally? There's a few connectors you need to cut/lengthen, and a few that you won't need. Honda-swap had the best write-up I found when I did mine.

Re: wiring problems in my Z6 EF hatch, need some info
 

its an Si originaly

its had the Z6 swap since i've owned it so i dont know what all went into the swap.. you got a link for that site? or is it just honda-swap.com or somethin?

this is the one i found. hope it helps.

your si harness is obd1 correct?

so what injectors are you running?

Re: wiring problems in my Z6 EF hatch, need some info
 

no the harness is OBD-0 with a boomslang conversion harness for the ECU and the dizzy plugs swapped over

running RC 550 injectors

and zex that page didnt really seem to help much :l that guy was goin assbackwards anyway..

heres the cliff notes


my car is an 89 Si EF hatch with a built Z6 turbo swap
i have a brand new uncut harness to replace my last one that got tore up by falling and wrapping around the axle
need to change dizzy plugs to OBD-1 for the Z6 dizzy, need wiring diagram or info
square green plug i dont know what it goes to on the new harness (isnt one on my old harness)
is the injector wiring on the Si harness able to be left as is or are changes needed
running a chipped PO6 with boomslang conversion harness for OBD-0/OBD-1 and Z6 dizzy

lets see if im getting warmer. lol

Should help. Sensor wiring is easy, lengthen the stock harness coolant temp switch plug, plug it into the Z6 thermostat housing.

Dizzy wiring, the wires match up except for the fat white wire going to the grn/yel wire I believe, in any case the fat white wire goes to whichever wire doesn't match up on the OBD1 dizzy.

Grab a shop manual for the car and check the ECU code diagnostic section for a plug with matching wires to your extra one. How many wires are there on it and what colour is it? I'll go check my car tomorrow.

Re: wiring problems in my Z6 EF hatch, need some info
 

thanks for the info, and zex that page was a bit more helpful, lol, but im just spliceing the OBD-1 plugs into the harness so im not gonna mess with an adapter

the plug im talking about is green and has 5 wires going to it, 4 red with a black stripe and 1 yellow with a black stripe, on the other harness it looks like its injector wiring, etc, but it has a diffrent plug on it on the other harness... should i leave it as is or do i need to change it over?

Re: wiring problems in my Z6 EF hatch, need some info
 

Sounds like a resistor box plug, but I don't know the harness side colors, just the box side colors. I will check tomorrow in the daylight.

Re: wiring problems in my Z6 EF hatch, need some info
 

anyone?

Re: wiring problems in my Z6 EF hatch, need some info
 

the five wire green plug you speak of is for the resistor box.

If your rc injectors are low impedance then you need to get a resistor box in there.

If they are high impedance then, you're not going to use it and I would just wrap it in electrical tape so its not exposed.

Re: wiring problems in my Z6 EF hatch, need some info
 

people should really know what they are talking about before they post, you need to distribute the power of the yellow where the injector resistor box is to all the red ones, this will give the common signal to them all. the reason you dont have one on your other harness is because it was obviously completly switched over to obd-1 meaning non-peak and hold injectors. meaning you dont use a injector resistor box, basically just tap the wire in from the yellow/blk to every red/black wire on there (each one goes to an injector). and boo-yow theres your injectors.. yes you can keep stock obd-0 injectors as long as you have a injector resistor box wired in

the dizzy everywire color will be the same as long just connect same color to same. no you cannot stay with your obd-0 dizzy. if you are going to use this jumper harness..

if you are trying to stay in obd0 then yes you can use your stock si dizzy by drilling the top mount out to mount up to the top dizzy hole on the z6. the pm6 ecu will also work although vtec will not function and you will have to use some sort of controller, which will not control vtec the way its supposed to be.

good luck to you. pm me for more help i've done this a shitload of times.

Re: wiring problems in my Z6 EF hatch, need some info
 

yeah i actualy figured it out by lookin at it for about 5 minutes.. there was electrical tape around some of the wires and i undid it and figured out it was the common ground wire, its the OBD-1 connector thats been swapped in.. so i just swapped it over to the new harness

im not keeping OBD-0 injectors, i've never had any, but im wondering if the OBD-0 and OBD-1 plugs are the same because they look like they are.. i'll be installing the harness in about an hour anyway so i'll figure it out by then if no one knows before i do

Re: wiring problems in my Z6 EF hatch, need some info
 

yes your obd0 injector clips will clip onto obd1's

Re: wiring problems in my Z6 EF hatch, need some info
 

awsome, no pain in the ass in bay spliceing for me ;D

in the process right now of installing it... although i cant figure out where my throttle cable was hooked up originaly :l

i tried the spot on the intake mani but the holes dont line up.. so im gonna trial and error it untill somethin works
