As far as the build sheet stated, it had a manual originally. Someone or PO put the auto in because the TC or front driveshaft came apart and did some damage. So..... here we are with the 42 RLE and the proper 241 t case.
I took the center panel off, got the lower switch panel out and there was a plug not being used next to the locker switch. 4 wire flat plug that looks like it will be the OD off harness according to what I see on the back of the OD switches I see online. The block off plug for the other 3 plugs were never messed with judging by thye amount of dirt in all the little crannies.
Am I at least pretty close to assuming that is the OD harness?
That’s the plug for the OD if it was directly next to the locker switch. It should be white.
FYI I did a manual-to-auto swap as well and while my OD plug was there, most of the wiring terminated at the plug in the driver footwell and didn’t go to the PCM. I had to add all of this myself. You’ll need to see if that’s the case for you or there’s no point in adding the switch unless you’re up for the wiring.
That said, I do have an extra OD switch and pigtail if you want it for the cost of shipping. It’s just been sitting in a box of parts from the swap.
