again,, i have:
mugen chipped p28 ECU
skunk2 OBDII to OBDI jumper harness
99 Si driverside and rear trans mount
the question: im getting a GSR engine, should i get the OBDI or OBDII version, becuase i do have that choice, both USDM, and depending on which engine is the one to go with, What engine wireing harness do i use? one of the GSR's? or go and buy a 99-00civic SI engine wireing harness?? ---this is for a 99 civic hatchback--
if someone can answer this, life would be great.
thanks

btw.. you need the 99-00 si rear bracket, not rear mount.
and correct on the 99-00 si driver side mount.

you can either wire your stock harness for vtec..
or use the GSR harness.

obd.. well that all depends on the laws in your city. otherwise. obd-I

fowler!

Truthfully, I think the easiest way to do it would be to get an OBD2 motor. That way, you don't have to worry about your distributor or your injectors (different plugs between OBD's).

jonas

well yeah, obd-II if you want the ease.. obd-I if you want the please

If the ecu is obd1, then it doesnt matter. Stick with the obd2 motor, get a 99-00 si harness, add the iab sensor unless you are getting a sk2 manifold or dont care for secondaries and plug it in and go. I try to tell people this, but no one seems to listen. If you are running a p28 and a single stage manifold, its all plug and play with the si harness. You are gonna want the obd2 injectors, distributor and alternator so that it plugs in with the si harness (which will only work on 99-00 civics.)

No you can not use the gsr harness.

if i get the OBDI GSR engine with the complete harness from the engine to the ECU plugs, what computer plugs right up with that?
--or if i got the OBDII GSR engine with the harness from engine to ECU.. i could use my skunk2 jumper so that i can use my mugen chipped p28 and life would be cool? becuase all the plugs on the engine will still be connected for OBDII, but only the ones needed for OBDI would actually be functional and would work okay?
also i have the SKUNK2 intake mani for the GSR as well, which elimates some sensor i cant think of.

jonas

wierd. my friend used his gsr harness

I clicked on the link and it says the opposite of what you said. Driver side mount bracket and rear tranny mount. Which one is the typo?

I searched on HParts.com for the rear tranny mount and the part number that the site gave me isnt correct. Does anyone know the correct part number?

fowler!

This is what killed me when I first did my motor swap. We were trying to use the GSR harness and it wasn't working out.

Integras and 92-95 civics are set up with a two part harness. You have the engine harness and the cabin harness...where as, the 96-00 civics utilize a one piece harness. It wraps around the motor, then makes it's way into the cabin where it plugs into the ecu.

I'm not sure how much "extra" wiring there is, or if you can even do it, but an Integra harness is not meant to work on a 96-00 civic. 6th gens are weird like that

Driver side mount bracket and rear tranny mount

Also get the OBD2 engine and use the 99-00 si wire harness. If the engine is a 99-01 GSR you should be able to use that harness because all of the plugs are the same on the 99 up civics and Integras

I agree with fowler!!

I completed the same swap and used a 99 si wire harness and 99 si driver side mount mount and rear mount.

DR. ON POINT

Most of the crap in this thread is bull ****, if u do not know what u are talking about please do not respond in this thread.

You can not use a gsr wiring harness

You can not use a 99-00 civic si wiring harness, unless ur car is a 99 or 00

You must use the harness that came on ur car, or another harness ment for ur car (i.e. if u have a 96-98 dx u can use a 96-98 ex harness if u can find one)

You will need a 99civic si block mount. This is the mount that bolts to the actual block, right next to the timing belt.

You will also need a 99 civic si rear mount, the one that bolts to the back of the trans and block

You will need stock civic mounts for the rest of the swap

As far as wiring goes u are gonna have to repin a17 to a15 (not positive about those pins), u will have to rewire the IAC, CIA and the Crank Pully sensor, since u are getting a gsr engine u are also going to have to wire all the vtec bull ****

U will want to buy whatever motor ur car is (i.e. If u have a 96-98 civic u will want a 96-98 gsr engine, if u have a 99 or 00 u will want to buy a 99 00 engine, because there is a difference between OBD 2 and OBD 2.2)

hope that clears some stuff up

He HAS a 99EK! So he can use the 99-00 wire harness!

from the sound of it the GSR harness can't be used, but I was told (from a shop) if it is from the same gen you could use the GSR harness. But I'm not going to argue it because I've never tried.

I have a 97EK so I used a 96-98 EX harness for my B16A2.

Not to step on your toes, but have you done the swap? And do you know what you are talking about? I think a lot of people on here just read too much. I have done numerous swaps on ek's. Its already been made clear to use the 99-00 si engine harness and he also needs to use b-series mounts for: the front tranny mount, the a/c mount, not stock ones. The only stock mounts used are the upper tranny mount and the drivers side mount (not to be confused with the drivers side bracket). There is no pinning involved with using the si harness, you plug it and go. This harness will work on any obd2 b-series motor that is 96-01 or any b-series motor with obd2 injectors, distributor and alternator. And will work on 99-00 civics. Have a good day and good luck.

DR. ON POINT

my bad, I foroot to mention that u use the b series supplementary mounts

Yes I have done the swap before and the rewiring I was tlaking about was when using a 96-98 civic dx, cx or ex wiring harnss

Now that I know he has a 99 I would sayget hold of a civic si wiring harness to make eveything simple

EKen9

I am doing an OBDI b18c in my 98 CX and this is what I've found:

1. For mounts I need the Si rear bracket and the drivers side mount. I used the GS-R A/C mount (since I took out the A/C) and I needed the GS-R front tranny mount.

2. Use a 96-98 EX wiring harness or use CX harness and ad wires

3. Distributor plug is male and so is one on the harness. Took female end of GS-R harness and soldered onto wires on male plug. Injector plugs plugged in fine.

4.Still don't know if stock throttle wire will work on throttle (can anyone confirm this?)

5.Don't know how many plugs I'm supposed to have left over since OBDII harness on OBDI engine (can anyone confirm this?)

6. Needed a USDM p72 ecu or chipped p28 and a OBDII-OBDI conversion harness.

7. OBDI engine in OBDII car=pain in the fuking ***
