- Sat Nov 14, 2009 1:05 am #156496 Well i spent a better half of two days working on this since i got fed up with there being either auto harnesses or 92 civic harnesses (where the map is on the firewall and the wiring is in the chasis harness...) at my local junk yard and all the 5spd harnesses i needed where cut by idiots.....

Mainly did this so as to use a d series harness on a integra motor and i thought whilst i was working on figureing whats what i decided to go ahead and figure out everything just in case........and since i couldnt find the engine harness diagram in the repair manual i decided to do it myself

(Caution: I bare no responsibility for you screwing up its your fault not mine the harness i used was from a 92 civic 5spd so others may be different but so far i havent found any differentiation besides vtec and of coarse auto......so lets begin shall we)

Wires and plugs are not in order in any way i just did as i pleased lol....
And when i say the wires and their approx position im looking at the female end and the clip side up
And when color/ color comes up that means main color/stripe color

Now i also had at my disposal a 94 si harness from a 5spd so here we go

Vtec solinoid
2 plugs

1wire plug
Green/yellow

2 Wire plug
Blue/black
Black

and at the junkyard i just glanced at the only plug needed for the auto trans (that two tier thing that looks like a dual vtec solinoid oil pressure sensor......

2 wire plug
Green/black
and either Yellow or Yellow/white

Now look onto the next post I made to see the strut tower harness plug breakdown

- Sat Nov 14, 2009 1:05 am #156497 Engine harness part 2
i will first describe the plug by wire colors and area and then below the description of that side i will put where said wire goes....also I live in the US so when i say drivers side and passenger side if facing the engine at the front of the car Drivers side right, passenger side left.....

3 plugs(1 with no male connector just a blank plate)

No plug(the one with no plug going to it )
8 wires all yellow black

2 wire plug(drivers side)
2 wires from left to right

14 pin plug(drivers side)
14 wires distributed 3/4/4/3
Clip/top
1 2 3
4 5 6 7
8 9 10 11
12 13 14

^not perfect but you get the idea

Passenger side plugs
3 plugs 1 rogue wire

1 wire- White

14 possible pin harness....on the 92 civic with a nonvtec in it is a 9pin plug
on the 93+non vtec without the map sensor on the firewall its a 12 pin plug and on vtec cars where the map is on the top of the throttle body its a 14 pin plug

*=depending on what model your car is and what harness you may not have this wire there

2-Orange/black-02 sensor
*3-Green/yellow-Vtec solinoid 1 wire plug

10-Blank possibly for auto not sure what color

4 pin plug
1-red-inj 3
2-Brown-inj 4
3-Yellow-inj 1
4-Blue-inj 2

And there you have it one semi-complete engine harness wire set-up....Now so far from the two harnesses all plug wire colors are the same so you should be ok with this list....

Also using this list you can de-pin and re-pin the engine harness....and create a vtec harness or use any harness for your car really....

Enjoy and im open to comments as well.....

done

Race cars are like boats I guess. Time to bust out another thousand.

- Sun Nov 22, 2009 3:03 pm #157807 thank you so much for this, i deloomed my whole harness and forgot where some of the plugs went, but thanks to you and this post i was able to find where each plug went and everything, again thank you!

- Sat Feb 27, 2010 4:21 pm #178181 i have a 94 dx harness will this still work

- Sat Feb 27, 2010 5:18 pm #178189 yes

i noted some of the differences such as unlike yours mine came without the map sensor on top of the throttle body so it wasnt in the harness but i had a ex/si harness on hand that i also referenced from so this will help you

- Sat Feb 27, 2010 5:29 pm #178190 ok cuz i got a 94 harness but the air intake temp/iacv/knock did not have plugs on them just wires so i took some of a Da integra harness and iam trying to match colors
do u no what colors the knock sensor is

[teal_dx]

- Sat Feb 27, 2010 6:42 pm #178204 knock sensor is a single wire (black?) with a rubber connector on the end, but OBD1 cars didn't have them.

Do Not PM me your technical questions. Post them in the forum!

- Sat Feb 27, 2010 7:43 pm #178218 ok well i thought it is the green plug next to my oil filter and i also have that ruber one with the single black wire i have a 93 b18a1

- Mon Feb 21, 2011 5:20 am #239959 The black/red and brown/black thermostat housing wires arent connect to my house there just there.. (i bought the car like this, it was not running) i have a new dizzy in it thinking that was the problem for no spark.. but will these wires cause the motor not to have spark?


thanks,
ED3

- Mon Feb 21, 2011 4:17 pm #240029 well it is a ground and you need to have all your grounds connected in order for the engine to run properly...
