I've been looking around online at old forum threads and see differing answers on the compatibility of the digital overhead console and mirror upgrade. I know it's an old upgrade but I always wanted an R/T with it but mine came with the standard console. I have most of the power options from the factory on mine. It was nice to easily add the power outside mirrors. I haven't tried adding the power seat because my manual one is in perfect shape. I do want to add this digital overhead console over the winter when I'm not going to any car shows. It appears that I will have to get a console already with the plugs for the mirror and the digital computer. However, I'm confused as to what the compatibility is. I know in 2001 they changed the dash. I saw a guy add one to his 2001 on youtube and it worked but he didn't have ambient temp readings because that year was tied into the HVAC controls. It looks like in 1997, 1998, 1999, 2000, and 2001 all had different part numbers for the digital module itself. In 1999 the part number was 56045185AA, in 2000 it was 56045185AB, and 2001 it was 56045185AC when they changed the dash design. So am I correct that only 99-2000 years will work? I'm trying to buy the console, I really only need the module but the ones for sale on ebay don't specify what years they are. Is there a way to tell by looking at the plug? What changed?

You are correct in your concluding that only the 2000 and earlier versions will work. Between 2000 and 2001, Dakotas went from a CCD bus to a PCI bus, the multiplex communication system used for the various computer modules to communicate with each other. So a 2001 or later console will not communicate with a 2000 or earlier system. I'm attaching pictures of the console connectors from the 2000 FSM and the 2001 FSM. Unfortunately, they are both 12-pin connectors, but if you can see the wire colors, you may be able to tell the difference. Or if you can count the wires in the connector - the 2000 has nine wires, the 2001 has seven.

So if I get a unit from a 2000 Dodge Durango it should still work as long as the module has 9 wires? Looks like most of the ones I'm finding on ebay are all from Durangos. Most 2000 or 2001. I looked at a fsm for 2001 and did read about the new communication system to PCI. I never did find access to a 2000 manual. So the only video of an install on youtube is a guy doing it to a 2001 Dakota. He had to tap into 6 wires on the CTM. Would it still be the same to wire it up?

I'll attach the two wiring diagram pages for the overhead console from the 2000 FSM. The second page shows the two wires for the CCD communication. You can probably wire them into the CTM, or you could also wire into the data link connector. The wires for the lights (pins 5, 6, 12) are probably already there. The other three wires all go to connector C3 on the back side of the junction block (interior fuse panel). I'll also attach a picture of that.

Looks like I've found one for sale with the connector. It has 9 wires. The seller has no idea what year or if it was a Dakota or Durango. I may get that one. It's not too badly priced.

I got the overhead console in the mail today. It's got the plug with 9 wires. I've got my 99 wiring diagram. I assume I will cut my standard overhead console connector off and splice in the new connector wires by color and looks like I'll have to splice the 6 remaining wires into the CTM wiring corresponding colored wires. The seller said it was from a 2000 Dodge Durango. I called the dealer and asked what year range the digital module would be compatible with for my 99. I think he said 98-2001. The part number it shows for my 99 they said changed to the same part number for the 2000 Dodge Durango so hopefully it works right. Now I just need to get the auto dimming mirror. Which I will assume splices into the overhead console connector?

I cannot find a wiring diagram for the automatic mirror in the 2000 FSM. The option is discussed in Chapter 8T - Power Mirror Systems.

In the 2001 FSM, there is a wiring diagram, and it appears the mirror has a separate 3-wire harness -- power, ground, and backup light input. This harness apparently terminates at the Junction Block, connector 3. Let me know if you want the diagram from the 2001 FSM.

I would guess that if you don't want the backup light option (disables automatic dimming when in reverse), you could just wire in the power and ground wires from the overhead console.

I've got the 99 service manual and I found the diagram for the mirror. I will likely have the overhead console and mirror wired up while my 99 R/T is in the shop getting the original muffler and tail pipe put on. My mechanic is a specialist in electrical, they've done some wiring for me before on my Ranger. I'm not sure if they know this upgrade for the Dakotas. Is there anything that I need to tell them to look out for? I know the guy in the video was twisting the wires together, but I'm sure they know to do that. I'll take the headliner out and the kick panels to save some labor plus they can route it down the factory area. I'm going to order the mirror with the connector.

If your mechanic is experienced in electrical and has the wiring diagrams, he should be able to get it all done up nicely. Hope everything works with the unit you bought. Enjoy it!

I talked to the mechanic yesterday and they said it shouldn't be a problem. I told them I would remove the driver's side kick panel and the headliner to make it easier to route the wiring. Is there anything else I might want to remove to make it easier for them plus to save labor? Any idea of how long it would take to do the wire splicing? I'm trying to get an idea of how long it should take someone who knows how to do it. I picked up the auto dimming mirror today which actually came out of a 2007 Grand Cherokee. It had the correct most recent part number on it for my 99 R/T. Some were saying it should work but didn't match the original style. It was only $11 and I got the pigtail that plugs into it, that has 3 wires.

If you're removing the kick panel for access to the CTM, it may not be there on the 99/00. According to the FSM, it's tucked to the right of the glove box opening. You may want to check that.

It doesn't appear on a 99 you have to wire into the CTM. Looks like just the junction block Connector 3 on the driver's side. Doesn't look like anything has to be spliced into the CTM. I know the youtube video one was an 01 and he was splicing into the CTM on the driver's side. There's a WT/BL and VT/BR wire that goes from the joint connector 3 already to the CTM. That's the only wires that should already be there. Unless I'm reading the wiring diagram wrong. I'm semi-ok at reading these. They aren't as simple as the 60's and 70's Mopar wiring diagrams I learned from. While I'm asking about this, while at the salvage yard I picked up an ambient temp sensor. I already it installed it to the radiator support. Will it cause any battery drain if I plug it in without the console being installed yet or just leave unplugged?

I'm pretty sure the ambient temp sensor will not cause a battery drain. It only works with the overhead console, and it only has power for the computer functions when the ignition is on.
