T-56 Swap, M6 wiring harness, M6 flash, question withing on reverse lights
OK so i completed the conversion to a T-56 from 4L60E, I changed the wiring harness and think that I may have to do some repinning on the PCM as far as the reverse lights go but don't know for sure what.
With the M-6 harness why wouldn't my reverse lights work? I programmed using the M-6 flash and adding in all of my parameters and still no lights. Can anyone offer some insight to this?

If you replaed the entire harness, the I'm not sure what exactly is going on.
On mine, i just bought the revers lt pigtail for the t-56 from GM...spliced it into the correct wires that came off the automatic shifter, works perfect.
Used this write-up, its very nice.

Re: T-56 Swap, M6 wiring harness, M6 flash, question withing on reverse lights
here is the blurb on the reverse light wiring
Next, the 16 guage brown and green wire needs to be wired to the reverse light connector. Test this first by connecting them together. If the reverse lights do not turn on, find out what the problem is before continuing. Otherwise, connect them to the reserve light pigtail which plugs into the driver side connector on the tranny. Polarity is not relavent here. Test this again by putting the car in reverse and checking for the reverse lights to come on

Thanks Birdman, I'm baffled....
The whole reason for putting in th4 M-6 wiring haness in was so I could make it look stock
I didn't want to run the wires out but it looks like I.m going to have to,
