Currently at the tail end of my build swapped a 86 turbo 5 speed into my 87 na auto z31 I have everything in already and all I’m fighting with now is trying to connect the turbo wiring harness into my non turbo chassis harness is that even a thing? Can I do that? Should I do that I’m at a loss a lot of plugs on the passenger side plug right in to the chassis harness but my issue is im not getting spark when I crank it off of the alternator are 3 plugs and 2 out of 3 plug in but one doesn’t I’ll post picks of the one that isn’t I’ve been messing with it for months and am at a loss if anyone has any info or has done this before please lmk or txt me 4062157727

 

The two pin could be the turbo Knock Sensor. Turbos have them, N/As do not. Use the service manual wiring and look at Turbo vs N/A. Both are in the same manual. Good luck.
