Switched power fuse tap in 2001 E250 engine bay

[rob_gendreau]

Anyone got a suggestion for a good fuse to tap in the engine bay fuse box for switched power on my 2001 E250? Seems like everything's hot or not on via the ignition switch. There are some unused slots, but they don't seem to work either.

Or, failing that, any wire I could tap into? I hate using the in-cockpit fuse box since it's a tight fit on my van.

There's a 4-pin round connector on the windshield cowling, next to the washer fluid filler. If you don't have the factory aux battery, this connector will have a single wire jumper in it. This jumper has switched power, and you can splice directly into that jumper.

There's also the power distribution box under the hood, and you can tap off any of the fuses using a fuse tap. You'll just have to test-light which ones are switched. There may even be an unused relay you can plug a spade terminal into, such as the trailer Battery Charge circuit if you don't have that already hooked up.

I'll check, thanks. None of the other fuses worked, sadly.
