Will Dakota Digital VHX dash for 82-92 http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=962/category_id=422/mode=prod/prd962.htm work with an LS3/4L65E erod swap with this Dakota Digital OBD-II/CAN interface http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=752/category_id=646/mode=prod/prd752.htm to help keep my dash the same. Just want to pass anything CA smog ref checks for.

 

 

I have those two units from Dakota Digital. I'm just finishing up my LS1/T56 swap (click the link in my signature).

I had a high idle that set two codes, a P0507 for High Idle, and a P0650 Malfunction Indicator Lamp (MIL) Control Circuit. I changed the idle air control valve and the idle is fine now. I cleared the codes, but haven't run the car long enough to see if anything comes back. I don't have the CEL light wired directly from the PCM to the cluster control box as the factory LS1 does. Instead, I have it come from the OBDII port -> Interface -> cluster. This may be why the PCM didn't think the CEL was functioning properly since it wasn't 'sensing' the bulb. I plan on wiring up an LED near the PCM that is wired directly to the PCM just in case.

Can't really help you on anything else as far as smog or the auto trans.

 

The DD dash has provisions for an LED IN the cluster, you just need to wire it up, just like the high beam, turn signals etc, so you should need to just wire from the ECM to the DD box

 

Yup, I know, that's how I knew it threw a code. Since I have the DD OBDII interface, the cluster gets the CEL signal thru the DD OBDII interface from the PCM, which then illuminates the CEL. Since the CEL signal comes thru the DD OBDII interface, I didn't run the separate wire from the PCM to the cluster control box as I thought it'd be a bit redundant. I suppose now that if I ran the wire from the PCM straight to the control box, I may not have gotten the P0650 code. (Not sure what would happen if I did that in addition to having the ODBII interface... that might be a question for DD). Either way, the additional LED I was going to add is for the sole purpose of making sure I don't get the P0650 code rather than adding a single wire to my harness that part is finished and loomed on my project. I already have a nice spot for the new LED next to my OBDI port and airbag LED under the passenger dash.

It was more just for the OP, that when he does the wiring to go ahead and run the CEL wire from the PCM to the control box even if he is using the DD OBDII interface.

 

Erod doesnt require any specific gauge/s to pass the ref inspection.Any gauge option will do, your choice.All the instruction say is stock gauges will not work.
