Whoops... What could I have done?

That's right. No lights....

 

if you had an OV tune kit i would suggest you try to read your ecu.

 

yeah, same here. No CEL.

 

This is the reason I've never put the interior blue LED lights I wanted in the cab.

Seems the simplest shit can fuck these trucks up.

 

just gotta take the negative off the battery. then the electrical system is idiot proof

 

Looks like the gauge cluster is dead.. Tach and fuel gauge didnt move at all

 

Pull out the left side switch panel (it just pulls out) behind it you will fine a module, try reseating the plugs to them.

When I installed my remote start, I had to unplug one of those, when I unplugged it everything in the cluster shut off like in your video.

 

You should, though. I bought a set from Diode Dynamics, and they are great:

All looks good - I installed some switches here recently too so it was a good thought.

 

These newer cars are much more intollerant towards bad

Ouch. These newer cars are much more intolerant towards poor electrical skills. It's going to be very difficult if not impossible to remotely tell what you messed up down there. Tow it to the dealer and get it fixed.

 

I have an odb connector which is connecting to the ELM but not the ECU....

 

I am thinking you might of cooked the body control module to be honest.

 

Damn. I wonder what I could have done to do this? Just tapped the wrong fuse?

 

Sent voltage to a place it shouldnt of gone.

Maybe see if the local parts store has a obd reader. It should talk with the body control mod and give you either a no communication error or will tell you something. Lots of parts stores will rent out the readers for free assuming you will come back to them to buy the needed parts.

 

See his post #32 below

 

Recheck these three 10a fuses and inspect the short pin...the short pin is not a fuse but it does cut power to the ecu. If the dome light works the short pin is mostly likely good.

 

Dome light is good, short pin is good and those 10amps are all in tact

 

You're in a place that requires some understanding of engine control systems.

 

BALLS - I'll setup a tow for tomorrow. I'll keep you posted.

I've been contemplating a dual battery kit anyway - is this an excuse to isolate my toys from the essentials?
