94 S10 Blazer clicking under dash on acceleration

I have a 1994 S10 Blazer with the MFI 4.3 auto with 185k mi on it I just got done redoing the injectors, fuel pump, plugs and wires etc on and recently after removing my gauges to change the lights out to LEDs I started getting a clicking noise under the dash when I accelerate past 45mph up until about 80-90 when I let off it will stop for a few seconds and start back up. I thought it could be the speedometer cable but later learned that after 88 they changed to electronic sensors so that wouldn't be the issue. Anyone have any ideas as to what it could be and how to fix it? I'm mechanically inclined but I'm not an expert.

Sounds like the LED's job done it in.:lol2:

Check the wiring job.

Is the noise coming from speed odmeter head?

The LEDs were replacement 194s I simply placed in the stock sockets. I am not sure exactly where the sound is coming from, I just know it's coming from the drivers side under or inside the dash. I luckily haven't put it all back together yet.

can you hear it just setting there? if so take a piece of rubber hose and hold it to your ear and see if you can pen point the noise.

Also I had my radio stolen out of my truck last Monday, it was a Kenwood DDX 7019, and I replaced it with a Kenwood DNX 5120. The old radio was recovered but would not work after stolen out of the truck, I assumed it had been damaged beyond use and sold it for parts. The new radio will work when connected via the power and ground wires to the cigarette lighter but when I wire it into a harness for the OEM connectors it will not get power. The 15A radio fuse and 30A accessory power fuses are both brand new and good. Any ideas? The factory radio appeared to work somewhat when I plugged it in also, but the screen did not come on.

Duid that happen before or after the other problem?
Got good theft insurance?
Get a good factory wiring diagram and a wiring diagram for the add on raido.
