Hey guys. I am underway on doing yet another EF b-series swap. This is the first time I am touching an EF. I want to stay OBD-0 on this because I am using a JDM SiR '89 head, and even though the block is a GSR, I can just leave the sensors that OBD-0 doesn't look for disconnected. Here is my issue: The car is a DX but the engine harness that I have is a true JDM B16 VTEC OBD-0 wiring harness, not just an Si harness. I know that it will not snap right in to the DX harness, but to be honest I would rather sit there and de-pin wires on the plugs if need be. I want to do as little wiring adding as possible. Is there a book out there on this? Has anyone done this swap with the true JDM VTEC harness before? I seem to be falling short a little bit on the search for this one.

 

You'll have to use the DX harness and convert your car from DPFI to MPFI. Since the block is OBD1 the coolant temp sensor will be on the water neck versus being on the back of the block like on the OBD0 engines, just FTW the plugs are different on the waterneck so you'll need to find the plug to wire it in. You'll also need to extend your IAT, TPS, and IACV wires for it to all work. All the other wires should plug and play besides adding VTEC and the secondary 02 sensor.

Use this to do the conversion and you'll be good to go

I'm almost 100% sure on this so can someone verify for me?

 

good **** man, thanks!

for your verification, the link to where you say "click here for a picture of the side you are looking at" the picture does not come up

also, do you have the pinouts for a crx crx sir? i think that would be a good addition to your table
