Worked great for me
It worked great for me. Had a flex fuel sensor issue and couldn't get HP Tuner to read file though the OBD2. Plugged the ecu into this and turned off the flex fuel sensor.

DO NOT POWER ON!!!!!!!!!! READ THIS FIRST! FIRST!!!!!
Pull the grey plastic cover off, has 6 plastic tabs you have to push in with a small screw driver. Now unwrap the electrical tape you will see 2 brass colored crimps holding the positive and negative wires together and there just wrapped touching each other aka a DIRECT SHORT!!! Rewrap them separately so they cannot touch and click the grey cover back on and your good, it will work. You can replace the 12v power adapter also if your worried because it is of very low quality and just barely enough Amperage to be safe for tuning. Personally 12v-2amp or 14v-2amp or I bought an adjustable 5-24v 3amp(75w) adapter and set it to 14v and when writing or reading it maybe brings the voltage down to 13.6v-13.8v which makes me feel very safe about not bricking a PCM but the OEM power supply did work after I fixed the short, it's your choice if you want to replace it for a better unit. Still shouldn't be this way but wasn't worth returning for the price because it was so cheap. Just buying the peices seperatly would cost more so your call. Happy Gen3, Gen4 Tuning guys!

Works as intended good buy
Works as intended when using HP tuners to Bench flash P01/P59 411 PCM's.Recommend double checking power supply wires are going to correct polarity based on other reviews but mine was correct out of box. Would recommend, saved me time over making one, well worth the $36 it costs.

Not correct
A wire was in the wrong pin location

Great product! Thank you
I did a fan conversion swap on a 2003 Tahoe. I was receiving issues with trying to flash the ecm while on the truck. Once I received this bench harness I was able to flash the truck and reinstall the ecm within minutes. My only issues was the plastic retainer that holds the blue caps on the connector won’t stay on, I think the little tab on the retainer is broken off or worn down. The cap stayed inside the ecm but I just flipped it over and it came right out. For the price and the convenience that this adds I would and will recommend it to anybody I know. Thank you again!

It will work.... Eventually
Check your wires

It's a good base to build from.
It needs to be upgraded to write to an ecm, but it's a great base to work from. Exceptional value given the cost of the individual parts.

Great concept, poor execution.
I purchased this so I could do off-board programming on a GM PCM (2005 Silverado 5.3.) The power supply was too small, most of the wires did not make it into the crimps, and the Ground wire did not connect to any of the ground pins of the PCM. Moving the ground, soldering all of the connections and jumper wiring it to a battery it almost worked. After programming, if you completely remove the power, the software stays but the VIN doesn't lock in, so I had to add a switch to the ignition lead, now it works fine. So really, I used the PCM connector and the DLC only, but I did get my truck done.
