Hi All,

I recently picked up a 1991 Nissan 90 HP. Great condition, but control box needed new ignition switch. I replaced that, got everything connected, but I'm getting no juice to the motor. No trim, starter wont crank, and no startup audible sound. Seems like I'm missing a cable connection somehwere. I did verify I can jump the starter and it will turn over. Any ideas? I know I'm missing a cable that connects the cable coming from the trim bracket back to the control box? Other wise, the main harness plug, 2 trim wires, and battery cables are connected where they should be.
Thanks!

Which red and red/white wire? It looks like I'm just missing wires to the tachometer/gauges? I'll take a couple pics of my connections when I get home later.
