Re: trouble getting vy/vx pcm to connect on bench
I think my bench harness has earth's wires from all connectors. Is there any wires from your middle connector?

Have you re-pinned it? Your ALDL wire appears to be connected to a tan wire, but on a stock loom ALDL would be red/black. I cant see what pin is what from that photo.

Re: trouble getting vy/vx pcm to connect on bench
I have checked connector E/F and the grounds are connected to E6/F6 instead of E7/F7. You also have the pinouts for the A/B and D/E connectors back to front with each other. A/B is the middle connector according to the numbering on the back of the socket on the pcm. Its also in the thread linked before, but possibly not so clear without reading through it all. Ive also posted this pic to the other thread to make it clearer for the next person.
Ive shown the location of the socket markings on this pic. Due to the angle of the camera the actual 'D' is not in the pic, but you can see enough.

Still no luck. I wonder if miswiring has fried something. I'll try connecting to it tomorrow in car. Or put my vy pcm on bench.

Is there a chance that it's my aldl adapter. It will connect to my cars but nothing with the on bench rig. What do you guys use?

Unlikely but possible. Our adaptors are recommended and are available from the for sale section. http://pcmhacking.net/forums/viewtopic.php?f=14&t=3616
