    b34 1.3 Motronic swap

    I'm collecting up parts for my m30b34. I plan to change the 1.1 Motronic to 1.3. The motor is going in a '89....

    I have:

    b35 179 ecu
    b35 Crank Trigger Wheel
    b35 CPS Bracket (w/ new oem sensor)

    What I need Still:

    Wiring harness. I was planning on using a manual trans b35 harness but, I'm having trouble finding one at the local yards. Other option being use my m20b25 harness. I would like to keep it with the motor though...

    Question: Am I missing anything else for the 1.3 conversion?
    Manual Trans m30b35 or m20b25 1.3 Harness is the only option?

      What about plug wires? b35 has some induction pick-up something or other...?? I got a new set of Bosch wires with the motor, hopefully they are right...

        You can use the m20 wires if needed.
