Alright so I've got the routing planned out for the sender. My question is with a 2003 Silverado can i simply use one of those "add a link" fuse holders to tap into the interior fuse panel for wiring if an electrical aftermarket gauge (autometer)?

 

If so which fuse is for constant and which could I use for switched ign power?

Check bbbindustries.com I believe it is. Last I knew they had free wiring diagrams still. Doesn't the dash cluster have a trans temp gauge? I've heard if not there's ways you can have it added to the cluster or swap the cluster and have it turned on in the ecm. Is this for everyday driving, racing application or something else?

(If this post is too long I apologize, please scroll to last sentence for my question) 

 

Thanks for replying, my truck didn't come with a trans temp gauge or factory trans cooler. I've seen the replacement clusters you speak of which run roughly $200 where they send you a complete replacement cluster with the option of LEDs to the color your choice, an optional replacement bezel and for an additional price they send you one with a OEM trans temp gauge in it which is supposed to be plug and play. 

 

They have one that you order and send yours in as the core. Another company has you send your cluster in to be soldered with new LEDs with the same options available as above for a slightly lower price. Pretty dang cool...

 

Since I already have an electric trans temp gauge (Autometer) on my work bench I'd like to install that in the Silverado. 

 

I've read a bit about using Retained accessory power, put there for upfitters that's located by my left foot in the center of cabin near the parking brake for ignition switched accessories. But I plan on using that down the line for accessories that draw more power like Auxiliary lights, amps, etc.

 

I was just wondering which fuses in the interior fuse box are switchable with the ignition and not always hot.

 

More specifically I'm wondering where others are running their aftermarket gauges to for switched power?

Grab a test light and start poking around.

 

I always use an underhood fuse as those tend to be better for switched power. Any of the o2 sensor fuses are switched and I've used those many times.

Not looking to tap in under the hood. Looking for a switchable fuse inside the cabin. Thanks for your input though.

Update: For other members looking for a switched 12V (ignition on only) power source inside the cabin fuse box: The SEO ACCY fuse (10A) is unused according to factory service manual. 

 

This is on a 2003 Silverado

 

It provides switched 12V power. Hope this helps someone. It's the one below my finger in the picture

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
