I went here http://www.geocities.com/civiczc/zcwire.html and a few ather places and all the HF to ZC wiring charts show A 7prong(HF) to a 5 and 2 prong plug(ZC). Here is what I have. On the HF side I have a 7 prong AND a 2 prong. On the ZC side I have a 7 prong AND a 2 prong. Unfortunately, the prongs are different shapes. But both of the 2 prong ones have the same color wires so those are taken care of. As for the two 7 prong ones, It's hard to tell I cleaned them off but it was still hard to see. Oh, both of the ZC ones are rectangular and the HF ones are round. Can someone lend me a hand here? Thanks.

From this and your other post, it almost sounds like you have the wrong ZC, but maybe not. I only say that because it sounds like you're describing a map sensor on top of the TB in your related post https://honda-tech.com/zerothread?id=235529

What color are the plugs on the distributor? Are they the same as your harness, or are they grey?

Remember that the very similar DOHC ZC came in a some of the Civic's over seas. I seem to remember it being a Special Edition 4 door or something like that. I have pictures somewhere. I know Katman posted pictures of it a few years ago. If that is an OBD1 motor is it possible that you have it instead of the 88-91 motor?

Wrong ZC? It is a black top just like the others I've seen posted. It's got PM7 on the cam gears as well as a few other places.

The connectors on the disributor on the ZC side are grey. They are off-white on the HF side.

If it is an OBD-1 engine, is this thing still going to work? How many HP on the special edition? Is there any way to "run" the engine vin number through Honda to see where it came from?

Grey plug means you did get the obd1 ZC. You need to buy a non-obd distributor and bolt it up. Make sure the plugs on the sistributor are the same milky white color as you plugs in your car. Also, you will need non-obd injectors. Maybe you should call up the place you bought it from and see if you can send the injectors and distributor back to them and have them send you the right stuff.

Will the one off my HF work or does it have to be off a ZC?

Update: I just called these guys and they said..."use you old distributor and intake manifold" ah....I have a HF and they want me to use THAT manifold on the ZC? Someone smoked too much crack last night As for the disributor could that work?

You need a ZC or a d16a1 distributor. Also, you need non-obd injectors. Dont even try to use the HF intake manifold. See if the plug from your MAP sensor will plug into that extra plug on your TB. I think the other guy is right from your other post, it is a MAP sensor. If you would like a ZC intake manifold, I do have one...I also have the injectors off my ZC. You never want to put any other intake manifold on a ZC, the only one that will fit is the d16a1 but it is more restrictive then the ZC.

I called they back and they are looking for non OBD-1 injectors and a non-obd-1 distibutor. As far as having a ZC manifold, one came with the car, so I'm good there.

What is a D16a1? Also, I have 2 dist. plugs on my HF harness, a 2 prong and a 7 prong. From what I've read, the 7 prong one needs to be split into a 2 prong and 5 prong plug. The 2 prong goes to the cam sensoe(where ever that is) and the 5 prong goes to the dist.. What do I do with the other 2 prong plug that is on the HF harness that originally plugged into the HF dist.?

d16a1 = 88-89 integra.

Call up this guy and see if he'll part out the dist. and injectors. Hes local.

i have a d16a1 distributor from a 88-89 teg! make me an offer and let me know if you want it! my email is t25_zc@yahoo.com

I have two questions. Oh, make that three or four...

Can I use my HF distributor?

and

If the dist. that I have on there now has 7 and 2 prong connectors and the HF harness also has 7 and 2 prong connectors, can't I just use the one that came with the ZC? If not , why?

For now, I'm going to try to mate the HF(OBD-0) dist. harness up to the ZC (OBD-1) harness. most of the colors match up, so I don't see why this won't work. As a side note, am I the first guy to swap one of these newer ZC's into a CRX? God, I hope not.

What about the injectors? Use the HF ones or the ZC ones? If they flow at the same rate I'll just use the HF to make my life easier. But if the Zc ones flow more I need to do some splicing. I set one of each next to each other and they are exactly the same except the Zc ones have 2 "guide" slots at the ends, where as, the HF ones only have 1 in the middle. I'm almost done guys, don't leave me now

If you use the OBD-1 injectors, don't you have to do something with the resistor? I thought I read something about that?

If you want to see a pic of my engine click here http://cgi.ebay.com/ebaymotors/ws/eB...tem=1844963114 this is not "my" enging for sale...actually, I have no idea who's it is, but that is exactly what it looks like, distibutor and all!

1990hondaHF

Why can't I use the OBD-1 injectors? The look identical. Can I use the HF ones instead?
