Default c2 connector: Pin a9

I have one wire left on my harness conversion. It comes from the c2 connector, Pin A9. It's a pink wire and it goes into the drive by wire harness. I've looked and looked and can't figure out where this goes? The pinout only labels it as "ignition one voltage." Does anyone know what this thing does?

Thanks,
Brandon

Ignition power for the TAC module.

Thanks for the reply. Man, now that I get it it looks simple, but it took me a minute to figure that diagram out. If I understand this correctly, the pink a9 wire just provides power to the TAC (drive by wire module), and so I would just hook this pink wire to a fused connection on the under hood fuseblock which would be powered by the ignition.

One semi-related question: When I purchase a fusebox for under my hood, there will need to be two different types of fused power, battery and ignition. From the diagrams I've seen I'll have one wire coming straight from the battery to power the battery hot fuses/wires and I'll have one wire coming from an ignition source powering the ignition-powered fuses/wires. Since one supply wire will power each of these types of fuses, how are they connected together? Do I have to manually connect all the fuses powered by the battery together, or when I buy the fuseblock will a certain number of them comes wired together and another group wired together. One group would be for batt, the other would be for ignition?

Thanks,
Brandon

A9 is your main ign hot key on and cranking. This powers the stock fuse block and all relays.

it just depends on what you buy... i think most fuse blocks will have individual wires for each side of each fuse and some may use a buss bar for one side that supplies power to all or several fuses and then individual wires on the outlet side. if you get one with individual wires on both sides you would just tie the ones together that you want supplied by the same source (battery or switched ign etc) and then route the individual outlet wires to each load.

one thing i would recommend would be rather than using the ignition switch as the actual power source for the switched power, i would use it to trigger a relay when on you turn the key to on/run and the relay will supply power to the ignition switched fuses directly from the battery. this way the ignition switch handles a smaller load and the load for the switched fuses will have to travel a shorter distance. this is kind of crude but hopefully explains it better than i can -


current performance sells a pretty nifty setup for this but kinda pricey for what it is though would take out alot of guesswork and save time
