Keeping this separate from my build, to make it easier for someone searching to find if anyone has similar issues.
So in my build Im using a wiring specialties harness. Made life easier to just plug and play however it for sure didnt make my life easier because of my mistakes. So some details:
76 280z efi, was auto when it was made, transferred to manual.
94 supra 2jzge na to t, 350z 6sp.
My issue begins with how do I wire up components like gauges, boost controller unit, AEM wideband unit, accessories and power in general?
So here is what I did:
I made my fusible link conversion to maxi fuses. I have that hooked up to positive on battery. I have another cable on positive to starter. I have my volt gauge wire hooked up to positive. Also have my relay for headlights to positive on battery. My headlights, signals and brakes work fine. 2jz need a cable from the alternator to the starter to recharge it.
The negative terminal has the chassis, engine and headlight relay grounds.
Now wiring specialties has a subharness thats for the fuses and relays. Has wires such as fan switch, reverse switch, a/c, oil press, CEL, coolant, speedo, tach, and Now the important ones, Alt light, start signal, and ignition +.
The start signal is hooked up to the back of the ignition cylinder BLACK with YELLOW wire.
I have hooked up alt light, ignition +, my speedhut gauges +, aem wideband + and profec controller + to the back of the ignition cylinder the WHITE with RED wire. Now thats where my problems start.
Seems to give me constant power with NO key in. Looking at the wiring diagram it seems like that wire is a good choice so im not sure whats happening? It also primes my fuel pump with no key, which im sure will be fixed with the correct wires. The diagram shows it stages from ACC, ON, START.
On a side note connecting my speed hut gauges the back light doesnt come on when the gauges were on. Im pretty sure I connected it to the wrong wire. Looking at the colored diagram should I hook them up to the RED with Blue wire? I think I connected it to the green with white on the tach which isnt good.
High beam light comes on with low beam light and off at high. Connect that to the RED wire? I dont recall which one I connected it too but figured id ask.
I appreciate any help. Wiring isnt my strong suit but I do my best to understand it but this has me stumped since its a 12v switched ignition.
