I will be swapping my OBD0 B18A1 into my EG soon, and was wondering if I got everything straightened out as far as what I'll need. You guys are way more experienced than I am, so I trust your opinion. Here goes...

Hydraulic tranny
B series shift linkage
Hasport mounts
B series axles
OBD1 Non-Vtec dizzy
OBD1 injectors
4 wire O2 sensor
OBD1 PR4 ECU

Am I missing any main parts? Right now wiring is my main concern. Does the engine harness from the EG plug into the engine harness from the OBD0 B18A1, with acceptions to the alternator plug? Thanks in advance.

 

I think you meant to say "does the Main harness from the EG plug into the engine harness of the B18"

But no. It doesn't. Use the original D series ENGINE harness, and just add/extend whatever plugs necessary.

That's what I meant Now I might have my "harnesses" mixed up here. The main harness is the harness on the engine that is a ton of wires? Then other items like dizzy, injectors, alternator, etc are other wires? So one I change the dizzy, injectors, and other obd0-obd1 conversion items on the B18a1, then I use the main harness from the D on the B18a1? Making all the cream connectors, obd0, eliminated and all the connectors now grey connectors, obd1, on the b18a1? Originally I didn't think that the harness on the engine could be removed, like the wires coming from all the sensors etc. I thought you had to plug those ends coming out of the motor, into the D harness. Sorry that was mad confusing.

 

lol, that was very confusing. I'll try to clear it up.

You have two harnesses. The Chassis harness, which is all the underdash harness, the fuse panels, etc.

Then you have the engine harness, the one with all the sensor plugs, injectors, etc.

You want to use the original D series engine harness on the B18. They come off, don't worry, just take your time, and if you don't recognize it, label them as they come off the plugs

 

Ok, kind of following you...

The B18A1 that I have came with an engine harness. I'm removing that harness, and taking my D16Z6 harness off and putting it on the B, correct? Then that way, the chassis harness, from the eg, will plug into the "new" engine harness, from the D put on the B.

Bingo

 

You're the man! Everything makes complete sense now.

Would it be easier to get a obd1 b18a1 or b18b1 harness? I read some wires need to be extended from the D, or is that only the thermostat/fan switch wire? Also, a P75 will plug into my chassis harness, where the P28 used to be, correct?

The ECU will plug in just fine.

The problem with using the "swap" engine harness, is that a B series engine harness won't plug into the stock D series chassis harness. That's why it's a rule of thumb to keep and reuse the original engine harness for the car.
