Sweet. Was just wandering why they were different. That's what I suspected.

Bringing this back up, mine didn't last 3 years. I put new batteries in and my connector under the turbo started smoking. They were Alliant so i guess im going to try the SD for the driver side, i didn't like the connector under there anyways. I have the wire diagram for the obs style, does anyone have the sd one?

I did look on amazon and you can get both sides, glow plugs and a relay for $90...... seems completely legit...

Haaa not happening here, just going back to RR. It was amazing to see what knock offs are offered. Makes me not want to buy an older diesel in the future, some idiot get one running and sell immediately.

Here's a decent writeup from 410customs on the changeover (with diagram): "OBS UVCH upgrade to Superduty - How I did it". Cheers!

Well I just finish this project today I said screw it on all the diagrams and I just used a continuity tester on both harnesses to figure out where they went it is very straightforward
