Think I got the wiring issue resolved-just need to connect it all together. Turns out I had looked at the wiring diagram for another Z model. The J model has 3 wires into/out of the ig switch. Will update for sure here.
Will have to wait as looks like my stalling/engine cut out issue was due to an aftermarket ecu failing. Hoedar. Runs fine with the stock back in place. Looking at other options now for ecu. Ecotrons....Aracer? thoughts?
