ok, i just put this obd1 d16y8 dizzy on with my y8 into crx swap and i followed all the wiring as stated in the instructions i got but there is one solid green wire left and i dont know where it goes.

- obd0 = 7 wires plus the 2 ( blk/ylw & blue )
- obd1 = 8 wires plus the 2 ( blk/ylw & blue )

this is wat the instructions say........

OBD0 OBD1

thick white ylw/grn
thin white white
org org
wht/blu white/blue
blu/ylw blu/ylw
blu/grn blu/grn

all of these colors are hooked up but the is still one solid green one coming out of the y8 dizzy, but i have no clue where it goes

PLEASE HELP


here is picture of my dizzy and green wire

also, on the 2 prong plug on the vtech solenoid (green) , is one of those just a ground? there is only 1 wire to go to it in the instructions?


THANKS!

 

try this out, http://diy.prostreetonline.com...id=40

dunno if that helps.

Also your pic dont work.

 

The Y8 distributor is OBD2 not OBD1. The wire colors for obd0, 1, and 2 are as follows:

OBD0
1Orange
2White
3Orange/Blue
4White/Blue
5Blue/Green
6Blue/Yellow
7Large White
8Black/Yellow
9Blue

OBD1
1Orange
2White
3Orange/Blue
4White/Blue
5Blue/Green
6Blue/Yellow
7Yellow/Green
8Black/Yellow
9Blue

OBD2
1Dark Blue
2White
3Green
4Red
5Yellow
6Black
7Yellow/Green
8Black/Yellow
9Blue

 

Yes the VTEC Oil Switch is the green plug on the solenoid and one of the wires a ground.



You can see that the top wire is for ground

 

ok, thanks alot for the help! also do u know where the knock sensor and service check signal is located?

can i use the a6 dizzy on my y8, does it matter for vtec or look for a z6 dizzy?

thanks

 

Not the best pic but you can see its above the oil filter with the green plug going into it.

You can use the A6 dizzy on the Y8 as long as you are using the crx's ECU. How are you activating VTEC? The Z6 dizzy wouldn't work unless you are using a P28 ECU anyway plus the "legs" of the distributor don't line up as well as the A6 dizzy does.

 

this is the set up i am trying to finish = obd0 to obd1 conversion wiring harness form total performance racing, y8 head and block, si tranny, p28 ecu ("vtec activation"), y8 im and tb, not sure which dizzy will work best, z6?

i am hoping i installed the y8 intake manifold right, i fitted the intake temp into the cai right before the tb, and use the plug in from the old si map on the fire wall which plugged right into the map on the y8 tb. what should i do with the old si map on the firewal along with the charcoal canister and stuff, they are vacum operated and the map is a sensor i guess.

 

i just found out why i could not find the knock sensor, there is the bolt srewed into it. the bolt/sensor/plug thing is gone, so i gotta find one, lol.

 

how much would a knock sensor with plug, vtech (green) 2 wire plug cost me if u got it?

 

also, in ur picture, see the black plug right by the oil filter underneth the metal piping, wat is that called (sensor)?

thanks

 

You won't need a knock sensor for the Y8 if you are using a P28 because it doesn't look for it. You can remove all the old map sensor items but I would leave the charcoal canister because its possible you will have a gas odor if you remove it. The black plug I believe is the fan switch plug.

 

so i shouldnt need the ks even though is says to hook it up in the instructions?

there is one vacum line coming from the cansister still to the old map sensor, should i plug that or leave it open? do u think pluging the old map sensor to the y8 map on the tb will work fine? so far i have hooked up the vtech signal and pressure signals, have the knock sensor ready to be pluged in, 4 wire o2 sensor ready to be pluged in once i find one. must i get a secondary o2 sensor after the cat too?

 

1. No the P28 ECU doesn't look for knock. The harness is generic and is for most swaps (B16A, B18C, etc) which have knock sensors, but the knock sensor in your case won't be used because of the ECU doesn't look for a knock because the D16Z6 (the P28 is for the D16Z6) doesn't have one. Just put a wire nut on the end of that wire from the conversion harness and tuck it away.


2. You can get rid of the map assembly all together and plug any of the vacuum lines that came off the intake manifold to it.

3.Yes the map sensors read identical, I used a Z6 map sensor with my swap (89 CRX Si w/ D16Z6 swap) and it worked fine.


4. No secondary O2 since the P28 doesn't look for anything but the one 4 wire O2. Just make sure that the placement of the O2 sensor is on the exhaust manifold or header right before the catalytic converter as opposed to right near the head as on the DX manifold. If you get an aftermarket header get one for a Z6 or Y8. Other than that you should be straight.

 

how are u getting these pics up on the post. i have a digi and i have pics already transfered to my computer. i could put up pics of these things to for you and evryone else who reads the forum. by the way thanks for your, other people who run into the same problems could also use this to help them too.

the map snesor on mine is on the top of the throttle body with no vacum lines, should make a diff?

nope you just wont need the vaccume line that runs from the t/b to the old map sensor in fact you can rid of the map sensor and the purge soilinoid and the charcoal canister just make sure you run the vent line from the gas tank safley outside the car and not in the engine bay like it is now

 

is the gas vent the hose coming through the firewall? the one i need to vent outside the car
