I don't know. I'll find out when I get it back. They said they added/changed some hardware. Either way, probably only needed on 1000+ builds. Chris@IW is pretty awesome. Almost as nice as Chris@ECS.

Getting the balancer back in time should not be an issue. Having enough time to work out other gerlims after the fuel pump/tranny swap is my concern. If that has to be redone or messed with, it will be tight. Car hasn't been driven since that.

So put interior/shifter back together. Next thing I can do is wire in the hobbs switch for the 2/3 pump. Was going to tap the red line to the alky control map sensor. Need a easy to grab >6V source. Not sure if the red wire on the map sensor is 5v or 12V. I think it is switch 12V but not sure and battery isn't hooked up to meter it.

Hmm, best cleanest place to pull 12V for the hobbs switch?

Unfortunately I don't have a good answer on that one. I usually just go through circuits in the underhood fuse box and use one of those add a circuit things to tap into one that does what I want

What about using the Hobbs for the ground side of the relay? I assume you are running a fuse and relay to power the pump/pumps? I used the ALT post for the 12V and wired the Hobbs to the frame ground on the drivers side. Mounted the Hobbs right next to the alternator and used it to ground the relay.

Can't. Fore FC3 controller, not a relay. So it needs a 6v+ signal to switch.

Gotcha. You would be adding a relay for nothing basically. Where are you going to mount the controller?

Last time I needed a keyed hot under the hood I pulled it from the coil harness.

Yah, coil harness is there. I could also tap to the alternator.

Controller is mounted in fender, but may move it to the rear cubby later. By the time I noticed it said internal use only, I already had it done. A few weeks mounted up by the gas filler won't hurt it.

Looking at tapping 1 of the 3 alternator wires out of the weather pack on the alternator. Isn't 1 of them 12V switched? I rather tap that then the coil pack harness.

The 12v wire isn't keyed. It's on all the time.. It's The one that works the horn.

I would think a 12V hot all the time would be fine for this.. it won't be doing anything until hobbs switch says go anyways

Red and white alt wire if you want a 12v hot all the time

Hot all the time is fine. Since I have the billet tech alt with extension seems easy to tap into the extension.

So just tap into the red wire on the extension harness should work great. One into the hobbs, other out to the Fore FC3 controller.
