1991 Crx HF Engine swap help
Hello I have researched alot of threads and am coming up blank with this particular situation.
We have a 5 speed 1991 Honda CRX HF with a blown D15B6 non vtec. I purchased a D15b Dual Stage vtec JDM engine from ebay aswell as the below listed parts. But nothing is matching up. Only 2 plugs from the harness go into the ECU and we have multiple plugs left over that do not match up with the engine. Can anyone shed some help / parts list of what we need and where we went wrong it would be greatly appreciated.
If i missed a thread that contains this info I am sorry, i know it can be frustrating when a person signs up and asks something thats already been answered multiple times, i did spend time researching it and most threads i found were for the Vtec-e engine.

You need to use the original HF engine harness that came on the car and make the necessary wiring changes to it, like distributor connectors, cooling fan switch, etc. The HF harness has the white wire for the igniter in the driver's side firewall connector, not on the passenger side connector like most other MPFI harnesses. The injector wiring is a separate little harness that is taped into the engine wiring harness. Open up the harness and you can replace the OBD0 injector wiring with OBD1/OBD2 injector wiring. You would also need the ECU jumper harness.

Sorry i got shipped off for work and only just got back around to having an internet connection. I did get the rywire plugs that another person said i needed that go into the ECU. About to start back on this over the weekend. So its really just splicing wires around? i understand that i would not be able to use the dual stage vtec and instead its going to be single. Anything else i would need to know? already have the transmission etc.
