02 Mustang GT Diagram Help

[scotty113x]

I'm new, i have a 2002 GT with a parasitic drain. It is narrowed down to the MAXI Fuse 7 in the Engine bay and Fuse 37 under the drivers side. Does anybody have a wiring diagram they they could share? I'm trying to find out what exactly Fuse 37 powers so i can try to find the drain.

LMR has a nice chart on their site: LMR.com: 99-04 Fuse Panel

Or from the Owner's manual:

Looks like 37 is the "Adjustable Illumination". I think that's the lights that are dimmed by turning the headlight switch. If the headlights/parking lights are off, I don't think the interior lights should be powered, so there shouldn't be a draw with the headlight switch pushed all the way in. My Haynes manual wiring diagram shows it as fuse 13, but it is a labeled as a "Typical" drawing so I think that is from the 94-98 models. Still, it shows the switch should shut off the instrument panel lights, so if something is still drawing on that circuit, either the switch may be bad or someone wired something else to it.

Thread where 37 kept blowing, reply suggested to check the headlight switch:
2003 Mustang adjustable illumination fuse keeps blowing

Not sure why you are getting a reading on MAXI 7, it seems to be "Secondary Air Injection" but only on the 3.8L V6 (Owner's Manual says "Not Used"). Again, maybe someone used it to wire something to? Aftermarket alarm system, remote start, stereo, lighting, etc?

Any resolution on this? I have weird grounding issues on fuse 37. Like the fuse measures continuity to ground. That alongside with fuses, 35, 38, and 41.
