Axle probs YJ Please help
I have a stock 84 CJ7 with the Weber, the Nutter bypass and the TFI upgrade. I have removed the ECM and its wiring harness (only had to cut 1 wire) and have eliminated all vacuum except to the vacuum advance - no emissions, pulse air, etc. Got tired of not being able to work on it. Now the engine compartment is clean and sensible. I have kept all of my parts that have been removed and could replace them if necessary. My point is that it can be done and you don't need a new harness.
I would highly recommend the Nutter bypass and the TFI upgrade since you have moved to t he Weber. Take advantage of your new carb.
