Im trying to help a buddy with a car he jsut bought. To start off the wiring was hacked from hell...it seems there is an obd2 distributer..The numbers off the block are ZC 3002592.. My buddy just wants to do it right the first time so what harness should we use?? and if it is an obd2 motor could we use a obd0 zc dis..-harness cause we know were a parts zc integra is.. and help would be great thanks..

 

i dont think zc came in obd2 but maybe im wrong.. on my zc in my crx i used obdo ZC dist and the ZC cam sensor . ( which can be used from 88-89 integra) and a 89 integra ecu i used. i used stock crx SI wiring harness and just modified the two blue wires on the plug for dist to reach to the CAM sensor . u need a zc dist though. si ones and all that are diff cause of the cam sensor.

 

yeah i thot zc only came in obd0 but this is a obd2 distrubiter for sure wired up.. also there is NO came angle sensor on it there was on the teg but none on the zc but you could tell they put a plug in it and siliconed it up

 

came with obd1

 

motor could very be obd1 has the same plugs as the z6 distrubiter... what should i do then? use the teg dis,wiring,cam angle sensor and ecu??

 

ya they did come obd 1.. i think u can take that plug out and use the dizzy and cam angle from the 89 integ. and ecu and use 0bd0 si harness . i dunno if integ harness will plug into your cars harness or not

 

hmmmm if anyone else can confirm that or throw out more info that would be great

 

should i use the wiring harness off that 89 zc integra?? or buy another si one ( this one now is hacked up to hell) also what should i do about the intake manifold and tb? maybe throw on the zc one and make it obd0??

 

Just fix the stock harness if you can. Use the IM and TB included on the engine, no reason to change them.

 

naa this wirning harness is a mess id rather have him spend $100 on one and not give him more problems down the road thanks for everything guys

 

Get the correct harness for the chassis and go from there. Pick on up from your local wrecker or pick-a-part place and go from there.

If the motor is an obd1, you can get yourself a external cam sensor and dizzy from a 88-89 PG7 integra and make it work in your EF. Run the harness accordingly, as a A6 would go and everything will work out fine. You will have to re-pin the dizzy plug to the DX style square for the 6 pin plug and de-pin the 2 cam sensor wires (blue/yellow and blue/green) and run them off to the cam sensor, but other than that, everything will work fine.

 

the car is an si so ill run the si harnes.... i dont understand why you said dx? im going to run the dis and cam angle sensor off that 89 also the ecu maybe ill see if the harness is all a plug and play and ill run that also.. thanks alot for your help HT

 

You still need to add a couple things on your engine to fit in your car bruv,

The sensor for coolant temp will need to be extended.

The Left Engine Bracket needs to be swapped with the bracket off your stock D15/D16 engine

Pick up an 88-89 Integra Distributor to swap onto your ZC - slang the OBD-1 distributor you just pulled off - it sells well on ebay.

88-89 Integra Cam angle sensor - the front of your ZC should have a rubber blocked off plug - be really careful getting this thing out-if you're to harsh on it, you'll end up scratchin the inner bore which can lead to an annoying leak -this happened to me so heads up.

Extend the wire on the Firewall mounted MAP to the TB mounted MAP on your ZC

If you're gonna pick up an Si engine harness you'll need to mod the Distributor plug switch it from the larg circle plug to the small rectangular plug to fit the 88-89 teg distributor

swap out the "saturated" type injectors from your ZC to stock "peak and hold" type88-91 Si units -
should be it
find a PM6 ror PG7 to make it spin

you're set

 

lol thanks man well be gettin all those parts off that teg zc and using it on his car..
