98 Runner interior fuse box help

I am about to install a Cobra 18 WX STII CB in my rig. The unit comes with 3 wires out the back. Constant power, ACC and ground. I can use an add-a-fuse for the Acc. That was easy to find. BUT...there is only 1 constant pwr in the interior fuse box. That’s the 7.5a fuse SRS air bag light. Bank #21.

So here is the question. Would it be ok to tap into that SRS light for a constant pwr source? It would only be a 3a fuse. I can go straight to the battery but this would be easier.

Thanks everyone!!
