Update... Your comment about that wire connection got me curious, so I unplugged the locker ECU and returned the truck back to stock. Low and behold, the ECU is reading speed again, and the CEL is gone. I've been tormented by this for so long, and that's all it took. Thank you sir. Now I have...

What I ended up doing was making a "new" plug from a sourced pigtail. The plug hanging down is the original plug. I removed the green/orange wire from the original, and added it to the fabricated pigtail. It is not grounded. I didn't want to have the locker connect at an unsafe speed. I did...

Hey Charlie, I'm using an ECU I sourced from a junker that I took locker parts from. I used the diagram provided by Timmy. Now that I think about it, that diagram was for a 98, and I recall finding out after some help from you that wiring isn't the same in my 2000 as it is on 98s. I need to...

I'll give it a look. Thank you!

I've still got a P0500 that is plaguing me. I just had the combination meter rebuilt as I thought that was the issue. I wasn't getting signal from the cluster to the ECU. So I'm looking at replacing the ABS control module, even though the needles all move on the cluster. I have a 2000 SR5 3.4...

Nothing like a little zap to feel young again. LOL I appreciate the concern. Those lead extensions are insulated up to the very tip. At this point, I've checked wheel sensors and they seem to be good. I'm getting signal to the combination meter as evidenced by the speedo and tac functioning...

Bummer... Thank you again Charlie

Perfect. They're in Phoenix as well! Thank you!

I'm back to square one. The shop didn't diagnose the cluster for the p0500 code. They just tested the speedometer, and since it worked, they called it a day. I explained that I wasn't getting signal at the ECU from the speedometer, and they quickly responded that it must have a bad processor...

You don't happen to have the schematic for the circuit boards for a 2000 3.4 manual combination meter? Thank you again.

I did find a recommendation for a place in Texas. Relentless Motorsports

Full transparency. I'm trying to learn how to diagnose electrical problems. I have tested end to end, the orange/green wire that carries the vehicle speed signal to the ECU and recorded 0.6Ω. I tested that same wire to ground and recorded 3.034 MΩ. So then I started testing against other pins in...

I'm still chasing a p0500. I thought it was the cluster. It's not. I started poking around testing resistance in the wiring and I'm seeing roughly 3 MΩs when testing the resistance between the pins of the different connectors that plug into the combination meter, against the wire that send speed...

I ended up taking it to a local shop. Dick's Speedo-tac. They called me and let me know they didn't find anything wrong with it. I'm beginning to think I have a bad harness based on some testing I just did on resistance between the pins on the plug of interest. I checked out that Tanin company...

I'm looking for a good shop that can look at and hopefully repair my gauge cluster. I'm in Phoenix, but I'm open to shipping for a good recommendation. Thank you. 2000 SR5 5spd 3.4 CEL p0500. ECM is not getting signal from the cluster.
