I'm almost done with all of the wiring! Well, I think I'm done but I just have a few questions.

I'm swapping an obd1 d16z6 into a 90 STD hatch.

I'm done with the DPFI to MPFI wiring as well as the OBD0 to OBD1 wiring.

I just have a few questions about things I could not find in the tutorials that I read before I started the wiring.

First of all this valve on the back of the IM. I can't remember the name for it, but it wasn't mentioned in the conversion tutorials that I read.



I noticed that originally on the STD this sensor was located on the firewall and had this plug connected to it...



Should I extend these wires and plug them into the sensor on the d16z6? Or, are they not needed?

Also, there is an unused plug on the OBD0 wiring harness as seen in the first picture above, should I plug that into the sensor?

Here's another picture of the sensor I'm talking about. Does this need to be wired up? And if so, how?



Lastly, is this correct? I ran the red line from the canister to the nipple on the throttle body. There is an empty nipple on the top of this canister that I think I have to hook to the sensor I was talking about above, but I don't know for sure.



Thanks for the help! I am almost done! Here's a picture of my injector wiring...

I think the plug in the first pic is for something from the DPFI system... forget the name but I think the wires were orange and black. If that's it, it's not used for MPFI so just leave it.

The black thing is the Purge Control Solenoid Valve, and it is supposed to be plugged into that plug that's going to the firewall, so you'll have to extent those wires. Next connect a piece of vacuum hose from the charcoal canister (mystery nipple) to the valve, and if I remember correctly the valve needs a vacuum source. That whole system isn't vital, I left the canister and the valve out when I swapped in my B16 and haven't had a problem yet, though my car is a garage warrior.

You will have one plug left over from DPFI.....
I removed my Purge Control dealies, including the charcoal canister so I didn't have to worry about it......
MAP sensor is plugged in correctly.....
If you keep the purge control stuff you need to run the vacuum line all the way to the valve......

By any chance did you see my OBD-0 --> OBD-1 thread for any referencing needs?

Perfect! That's what I needed to know! Thanks!

I hadn't seen your thread but I just found it! I wish I would have found it before, there's a lot of good info. I'll go through it and make sure it agrees with all the wiring I already did.
