Dakota Digital HDX Install Write Up

Gear indicator for what?

for the transmission. I noticed in the photo, you didn't reinstall the stock indicator. I was wondering if you were going to use it or maybe something works with the gauges to show PRNOD21?

It can be shown on the gauges depending on the vehicle. For a square with a stock trans it requires an add on gear indicator module. With an LS engine/trans swap you can read it out of the pcm with an OBD2 module, I believe.

I just installed the VHX version. I had the option of covering up the stock gear selector with a supplied blocker, and using something on the gauge to tell me which gear I was in. I'm guessing that's what he's asking about since the gear selector wasn't in OP's photo? Might not have installed it yet I'm guessing? I left mine stock.

To the OP, do you have dual tanks? Mine work and all, but I literally have to turn the key to on (not started), make the switch on the dash, turn the key off, then start it up. Then, and ONLY then will the gauge show that I switched tanks. I reached out to Dakota for clarification, but haven't received a response as of yet. Still, pretty pleased with the install.

I just haven’t added it back in yet. Still deciding if I want to or not. I can function pretty well without it so not sure just yet

This is on my suburban so no I do not. That certainly seems odd

Wow, good information to know! Thank you for including that as it may be useful in the future. At this time, I don't plan to switch gauges in the dually but could change if I ever have issues with my speedo breaking in it or something like that. I'll definitely keep this info in mind if I do that and maybe it'll help someone else in their Google searches.

Quite welcome good sir!

Very nice write-up! I have the VHX gauges, and really love 'em. I'm digging the larger and more colorful LED info screens on your set. Looks like you get more than one line of info on those, which is great. The VHX has smaller LCD screens, which are still good, but not quite as pretty.

Yeah, those two screens are actually 4 screens in the configuration that I can customize to see whatever I want to see. It's pretty useful

Awesome write up! thanks for sharing. Maybe not related but how is your oil pressure? Is there much of a difference between the original distributor sensor location vs the Oil filter location?

Oil pressure while going down the hwy reads at 40-45 psi. With the old gauges that read from the old sensor (near the distributor) it was reading closer to 50 psi or a little higher. With that said, there’s nothing to say that the old sensor wasn’t giving an optimistic reading that wasn’t super accurate Overall, I’m satisfied with the readings and feel like the readings are pretty on point.

Do you remember what wire you used for the fuel? I've seen pin 18 or pin 7. Thanks. Mine has dual tanks.

I just finished my DD VHX cluster swap in my 1991 c1500 with factory ECM and engine. All gauges work great except the cruise control won’t engage and check engine light keeps popping on with code 24 for VSS. I have tried hooking the ECM wire to the speed out terminal and still no luck. I have spoke to DD several times and the last time they suggested I run a 2.7k resistor from the spd+ to Spd out and still no luck.They then suggested I change the speed output on the cluster to 4k ppm but cruise still isn’t working. I hate to say it but DD technical department has been no help and don’t seem to truly know what is needed to make this cluster function properly in our trucks! Right now I have the High speed connected to Spd Snd low speed connected to Spd- and brown ECM wire to Spd out.
Any info or help will be greatly appreciated.
