I just bought a D15B motor off of Japan Star Motors up in Albany NY and I have some problems. First of all, my IAT sensor was broken off in the intake manifold so I need to replace that. Also, my VTEC sensor and pressure switch connectors have been depinned but the plugs are still there. Well here's the thing, I don't know which wires are which on them so wiring my OBD-0 to OBD-1 conversion harness to them. If anyone can find me a wiring diagram or even point me in the right direction...that would be greeeeeaaaaat...m'kay Peter? I know one of the wires on the pressure switch gets grounded and one of them has to go to the computer. With the Xenocron harness, I have full instructions, but I can't tell which wires I need to put where on the two wire plug. If anyone can help me out, please do.

I totally picked up the line from Office Space

 

Are you running the p08 ECU or the p28? http://www.phearable.net/tech/...s.gif

This might help you out figuring out what wire go where.

d15 is the pin for where the IAT goes in.

 

I am running the P28 ECU. I'm not talking about connections at the ECU. I'm talking about the connectors at the VTEC Pressure Switch. I have two wires that I found that go to the switch. I know one is black and I can't remember what color the other wire is but they have been depinned from the plug. What I need to know is which wire goes in which side of the plug. This picture should help alot. Basically, the black goes on the right and the other on the left? Or is it the other way around? I'm angry because someone depinned them for what seems to be no reason so now I need to figure out where everything goes. But if someone can let me know, I'd appreciate it. Also, I bought one of those cheap *** aluminum underdrive pulleys from ebay and I need to know if anyone can tell me what belt size I need to get for my alternator. I only replaced it because I bought it for my D15B2 and it was the wrong one and the pulley that came on my JDM motor was chipped in quite a few places and rusted.

 

Anyone?

 

Take that POS back and make em give you one thats not all fawked up.

 

on the connector from the pic, the slot on the left(top of plug) goes to D6 the other slot goes to a ground anywhere on the motor or chasis

 

 

Dude, shove that search button. I'm not a fu*king retard. I don't know how I can make it any damn clearer, the picture didn't help put it in perspective? I DON'T NEED THE CONNECTIONS AT THE ECU AS STATED ABOVE. But thank you for the diagram as in a way that is what I asked for just wrong end. What I want to know is if you're looking at your VTEC Oil Pressure Switch connector (ON THE ENGINE) which wires go where in the connector. Someone took the wires out of the connector and I don't know where (on the two prong connector) the black wire and the other color wire go. All the you have to do is tell me, as your looking at the connector and the tab where it snaps into the sensor is facing up is the black wire closer to the windshield, or the radiator?

I'll check later tonight if nobody else helps you first

 

Chris Harris at Xenocron told me that it doesn't matter which one you use. He said that they can both be used.

Cool, then I'm taking my stock harness over right now with my new 4 wire O2 and my new IAT sensor and installing them. Problem is is that I need to go to Auto Zone today and get my new belt for my alternator. Auto Zone was the only ones that could help me when I bought my Unorthodox pulley for my Integra. I'm pulling my AC components right now. The rad's out, the condensor's out, the fuse block is out, the wiring is out, the headlights are almost out, upper rad support's almost out and my resistor box is out. Today's agenda is fix the exhaust on my minivan for my company vehicle, (an 89 Grand Voyager 2.5 turbo), and get the rest of the parts out ie: charcoal canister, fuel filter, battery tray, miscellaneous sensors and unneeded plugs, MAP sensor (which I no longer need), and that stupid fire retardant mat that sits behind the intake manifold (useless if you ask me). Then it's off to tow my car to my garage and pull what's left of the D15B2 and the Si tranny. I'm getting closer to having my car done with the D15B in and running. Oh, and I'm sorry for being a dick to freakystyley_73. I had JUST woke up for work at 1:00AM and I had 3 hours of sleep and I guess that's the common response to a commonly asked question. Sorry bro, took it out on the wrong person. Thanks for everyone's help and I'll keep everyone posted on the build. Wish me good luck!
