New headunit not powering on?

[95240sxdrift]

This may be a stupid question im new to the 240 game and i have a 95 s14 i hooked up a aftermarket headunit but it dose not want to power on and im not sure whats going on replaced the fuse under the dash and went to the fuse box under the hood and said there was a audio fuse that goes there but soon later found out that there was no connections in the whole section any help at all would be great thank you

The head units come with wiring instructions.




Typically red to red (power) black to black (ground) yellow to trigger (AC on)


you'd be better off showing a picture of how your unit is wired to the chassis harness than posting a picture of your fusebox...
