I am installing MSPNP on my MX-5, and since I have a slightly different ecu than the 90-93 I had ro relocate some wires In the ecu.


From stock my crankshaft sensor is wired to the 2F and a unidentified wire is conected to the 2E.

By reading on the forum I concluded that the crankshaft sensor should be relocated from 2F to 2E. This made the car start and idle

However, I still have a unidentified wire that originaly was wired to 2F and now is not conected (engine still running)

I tried to find a pinout picture of the PNP, in order to find out if the 2F are beeing used at all?

Is it is possible that the unidentified wire has something to do with the Immobilizer?

 

It *is* the immobilizer wire. I suspect they did this so you couldn't just grab the ECU from a non-immobilizer equipped car and drive off.

 

Should I just let it be unconected (2F)?

Do you know if there are any other wires that needs relocation? I did not have the time to idle the car for more than 1 min so there can maybe still be some wires that need relocation..

 

As far as we have seen, this is the only wire which needs to be relocated.
You can secure and tape off the immobilizer wire; it's no longer needed.

 

Thanks!
