Where to tap for power on engine-start?

[IPvFletch]

I've currently tapped my Halo lights into fuse F45 (ignition/cargo/accessory) but I'm looking for something that comes hot with engine start (but not hot when the engine is off). Any ideas?? I hate to play pin the tail on the donkey with electrical.. Fuel pump fuse??

Only thing I can think of is the spark plugs

Check the fuse for the rear 12v outlet. One position is always hot and the other is hot with ignition. The fuse can be swapped between those positions so I'm not sure which is hot vs ignition hot. Easy to check though.

Update - found it in the OM
1 — F81 Fuse 20A Yellow Rear Power Outlet (battery powered at all
times)
2 — F91 Fuse 20A Yellow Rear Power Outlet (powered when the
ignition switch is in the ON or ACC position)

I believe the manual may be incorrect on this. A few forum member's have mentioned there was no difference, regardless of fuse placement.

I think it is F43/F45 for 12v ACC and you can swap it depending on if you want it hot always or only with acc. That's what I'm using now, but I'm looking for IGNITION/START/ON though, not just Accessory.

If I remote start, it turns ON the engine, but NOT Accessory until I get in and hit the button.

Works exactly as listed in the manual. BTDT.

Ok, good to know. As I mentioned earlier, A few forum member's have mentioned there was no difference, regardless of fuse placement.

I finally got around to looking into this for myself...

WELL, if you move F81 to F82 and vice versa and see no change in power for the rear power outlet is is because the friggin manual is wrong.

What you need to do is move the yellow F43 to F45 or vice versa. In one position you have rear power outlet on all the time and the other position you have the rear power outlet only on when the ignition is in Acc or Run.

SO, go to where F43 and F45 resides, pull up on the fuse and move either to the left or right and then push down on the fuse..

See F43 and F45 circled in pic below:
