Photo Request: Looking for fuse to connect to in Engine Bay 6th Gen 4Runner

[ClarkeBar]

Oh electrical gurus of 6G4R.....I'm looking for which fuse *in the engine bay* to connect wire tap to for when engine is started. I'll be connecting that to my Garmin Power Switch for a control input. Also what size wire should I be using? I need all the help I can get LOL - Thanks in advance!

You should reference the thread I wrote for installing the ARB Compressor, specifically wiring leads to the driver-side fuse box. If you prefer to wire it to the box in the engine bay, that's a good reference.

I used the INJ fuse on the passenger side for Ignition power.

Yeah with the Garmin there is no need to go thru the firewall. The fuse box on passenger side is right next to the battery which has the Garmin on top of so at least a short run. Thanks!

@Trail4R I tried both the 20A IGT/INJ MAIN & the EFI MAIN below it 25A. Neither of them worked for me. The pics below are my drivers side fuse box on the TRD Sport Premium. At this point I don't know if I'm trying the correct location or if I'm just not doing the fuse tap correctly.

Try the 10amp IGN Fuse.

Thanks. Looks like I had my fuse tap in backwards as well, actually I see you have another going the other way was well. I do have a light tester coming in tomorrow so I can verify stuff. Thanks for your help. That picture helps a lot.

Yeah the other fuse is for another circuit on the ARB compressor.
