considering how readily available these are at a good price i had hoped someone would have mapped the power plug by now come on folks someone has to know where to find this info .

I just ordered two of these backplanes (w/o brackets) off eBay for less than $5 each w/shipping, but the 43V7070 backplane is for 2.5" drives, not 3.5" The power harness I found for two boards is IBM PN: 49Y5378, which has one 2x10 (not 2x12) supplying two 2x5 backplane connectors.

Does anyone know what the pin-out is for the 2x5 power connector on the backplane side? Or the 2x10 supply side?

Also, anyone know what the J11 and J17 connectors are for? One IBM pdf manual I saw referenced a configuration cable of some sort.

I am looking to use this back plane in a personal build and am wondering how I'd go about figuring out the pinout myself.
