Question about fuse box

[kappa67]

Hi all
I read this tread because I have problems with my aeroforce gauge (battery drain) and it is very good:
Wiring an Aeroforce Interceptor Scangauge
But how can I find the connector where I have only power when ignition current?
I have 2 fuse boxes....1 in the inside and one in the engine compartement
Please tell me both where this connector is.

thanks a lot
