The tech at Dakota Digital said I needed terminals 6 & 10. 10 is not there.

OK so I called them today & talked to a different tech. This one said I needed pins 6 & 14 just like you said. I tested the cable & its good, for some reason somethign isnt getting a connection when I put it in the ALDL connector, but if I put an extension cable in between them, it works.

Oil pressure doesnt work though. Original tech said if oil sensor has 3 wires it would work, well it didnt.

I still want to wire it direct, it only needs two wires. You suggest I tap into the back of the ALDL wires, or from the ECM? And do I need to twist them together?

THanks

Can't you use the stock oil pressure sensor and read it off the bus? That is what I did. Same for temperature, stock sender and read it off the bus.

Sorry for the bad advice on which pin the data is on.

I ran the CEL, VSS and Oil pressures off of the bulkhead connector. I realized after installing the BIM module I didn't have to use the CEL and VSS outputs of the bulkhead but I connected those wires (and the oil pressure wire) to the appropriate SND input on the control panel. I would use a stock oil press sender and connect it to the GMPP oil press plug (2 wires, grey and black) and use CAN for the sending unit type on the DD setup menu. Here is a picture of my OP sender. I am starting to swap in the new HDX gauges this week so I will post up pics of how I ran those wires specifically (installed thrm 3 years ago).

That's what I had hoped to do, but for some reason it's not working, tach, temp work from it, speed ist correct at the moment

I'm not certain how to direct wire the CAN connection since there is a terminator resistor at each end of it. Maybe call DD again?

Mine worked with a simple Y adaptor so that would imply just make a direct connection to the lines and do not add any terminations.
