INJ Fuse issues/dumb problem to have

What a problem to have...

I had a magnusson SC installed a few months ago; had it professionally done so I didn't know it tapped into the INJ fuse slot under the hood.

Bought the Icon IIC system and started wiring it up. The IIC wants to connect to the INJ fuse as well.

Anyone have insight on what I can do? the SC will obviously being staying in the INJ fuse spot...I'm not messing with the intercooler power. The IIC needs power 100% of the time while the vehicle is on, and needs to be drawing 0% while it is off.

Any help is appreciated.

 

Find another switched fuse to tap into. I think the power outlet is one.

 

Fused battery lead, 8 or 10 gauge, into the cab. I like MRBF or ANL fuses.

De-pin one of the power sockets and apply heat shrink then attach to a high current relay coil, I can give you a part number if you want.

Stuff that 8 or 10 gauge fused input to terminal 30 on the high current relay. Output from the relay to an 8 circuit fuse block. Doesn’t need to be waterproof since this is all in the cab. One circuit to a blue sea usb or power socket where the original power outlet used to be.

the other 7 circuits feed clean ignition switched power wherever you need them. Two to the engine bay for your SC and icon needs.

if it’s easier you can maxi fuse the power input in a kick panel and distribute it elsewhere as constant power. Like for a fridge or something which you don’t want to be ignition switched. Or do two fuse blocks, one off the high current relay and one off battery.

mine are under the cupholders. Probably space in the dash too just harder to access, rear seat storage / cubbies can work too, just longer runs.

then zero add a fuse taps needed. Which means clean Oem fuse boxes. Just the one battery tap.

 

Add a sealed relay in the engine bay. Fuse it appropriately, then wire this feed to pin 30. 87 to added circuit(s). 85 to ground. And 86 from add-a-fuse at INJ fuse.
Place smallest fuse in the INJ add-a-fuse (top).

Secure everything, done.
